A synergistic interfacial reinforcement strategy combining KH560 grafting and pectin-Ca 2+ crosslinking is developed. • Multi-scale interfaces (covalent/ionic/hydrogen bonds and entanglement) enhance filler-matrix compatibility. • The modified BF-K-P-Ca filler achieves a water contact angle of 120°, indicating effective hydrophobization. • The composite film exhibits tensile strength of 24.35 MPa and elongation at break of 593%. • The modification strategy enables industrial-scale film blowing for green biodegradable composites. In this study, PBAT, bamboo flour (BF), KH560, pectin, and calcium ions were used as starting materials to prepare PBAT/modified BF composites through chemical modification, melt blending, and blow molding processes. The effects of key process parameters such as pectin dosage and calcium ion dosage on the structure and properties of the products were systematically investigated. When the pectin dosage was 3%, calcium ion dosage was 2%, and BF dosage was 10%, the composite material achieved a transverse tensile strength of 24.35 MPa, a transverse elongation at break of 593%, a longitudinal tensile strength of 23.46 MPa, and a longitudinal elongation at break of 530%. The comprehensive properties were superior to those of composites prepared by traditional processes. The research results indicate that bamboo flour sequentially modified with KH560, pectin and calcium ions can effectively enhance the compatibility between the filler and the PBAT matrix, thereby significantly improving the overall performance of PBAT/BF composites. The PBAT/modified BF composites prepared in this study, due to their excellent mechanical properties, demonstrate broad application prospects in fields such as packaging, daily necessities, membrane materials, and disposable products.

The 0.2 phr KH560-MoS₂/epoxy nanocomposite exhibits optimal mechanical properties at both RT and 90 K. • Compared with neat epoxy, the 0.2 phr KH560-MoS 2 /EP system exhibits significantly improved liquid oxygen compatibility. • Combining 15 phr TAD with 0.2 phr KH560-MoS₂ yields high char residue and full liquid oxygen compatibility. Carbon fiber-reinforced epoxy composites exhibit significant lightweight potential for liquid oxygen (LOX) cryogenic tank applications. Nevertheless, their practical deployment is heavily constrained by the dual challenges of extreme cryogenic environment (90 K) and inherent incompatibility with liquid oxygen. Epoxy resins, when employed as matrices, cannot address the two critical challenges and hence need to be modified. In this study, epoxy resin is modified by grafting two-dimensional molybdenum disulfide (MoS 2 ) nanosheets with KH560 silane coupling agent. Mechanical properties of the modified epoxy system are systematically evaluated at room temperature (RT) and cryogenic temperature (90 K). The results show that at an optimal content of 0.2 phr, the incorporation of KH560-MoS 2 simultaneously enhances the mechanical properties at both RT and 90 K. Moreover, the liquid oxygen compatibility of the 0.2 phr KH560-MoS 2 /EP system is notably improved, and the epoxy nanocomposite further modified with 15 phr TAD and 0.2 phr KH560-MoS 2 can successfully pass the liquid oxygen compatibility test. These findings demonstrate that the proposed epoxy nanocomposite system exhibits enhanced mechanical properties and improved LOX compatibility, highlighting its potential as a matrix candidate for CFRP composites intended for cryogenic LOX tank applications.

In this study, a surface grafting modification strategy for TiO2 using the silane coupling agent γ-glycidoxypropyltrimethoxysilane (KH560) was employed, and a fluororesin-based anticorrosion coating with synergistic photogenerated cathodic protection and physical barrier effects was prepared by electrostatic spraying followed by thermal treatment. By combining microstructural characterization, photoelectrochemical performance analysis, and molecular dynamics simulations, the mechanisms by which photoresponsive behavior enhances corrosion protection performance were systematically investigated. The results indicate that KH560 can condense with surface hydroxyl groups on TiO2 to form Ti–O–Si covalent bonds, effectively suppress TiO2 agglomeration, and improve TiO2 dispersion and interfacial compatibility within the ethylene-chlorotrifluoroethylene (ECTFE) matrix, thereby producing a denser physical barrier. The long alkyl chains of KH560 further enhance the coating’s hydrophobicity (water contact angle = 96.8°). After modification, the coating showed a marked increase in photocurrent density, which is attributed to an enlarged photoresponsive area and improved charge-carrier separation efficiency resulting from better dispersion. This promotes migration of photogenerated electrons to the metallic substrate and enables sustained photogenerated cathodic protection. Consequently, in 3.5 wt % NaCl solution, KH560-TiO2/ECTFE exhibited optimal long-term protective performance under both lighting and dark conditions, and an appropriate TiO2 loading combined with surface modification did not readily induce oxidative degradation of the coating matrix. Molecular dynamics simulations revealed that KH560 modification reduces the system’s free-volume fraction and strengthens interfacial interactions between TiO2 and ECTFE, thereby effectively suppressing the diffusion of water molecules and chloride ions (with diffusion coefficients as low as 0.896 × 10–9 m2/s and 1.928 × 10–10 m2/s, respectively).

SiC is a promising functional ceramic material with many great properties. High concentrated SiC slurry with excellent rheology and stability is required in some processes of ceramic forming. In this work, the dispersion of SiC powders was obviously improved by ternary modifiers: γ-(2,3-epoxypropoxy) propytrimethoxysilane (KH560), sodium humate and sodium dodecyl sulfate (SDS). Modified SiC slurry showed the lowest viscosity of 0.168 Pa s at a solid content of 50 vol%. The maximum absolute value of zeta potential of SiC increased from 47.3 to 61.6 mV by modification. Sedimentation experiments showed that a highly stable suspension of modified SiC was obtained at pH 10. SiC green body with high density of 2.643 g/cm 3 was prepared with modified powders by slip casting. X-ray photoelectron spectra (XPS) and thermogravimetry (TG) measurements indicated the adsorption of modifiers on SiC surface. Therefore, modified SiC powders could stably disperse in aqueous media due to the increase of electrosteric repulsion between particles. The novel strategy used in this study could further improve the dispersion of SiC powders.

To develop multifunctional epoxy (EP) composites integrating good flame retardancy, suitable mechanical performance, and superior antibacterial properties, a nanosphere-shaped flame retardant (PDA@KH560-DOPO) was fabricated by grafting 9,10-dihydro-9-oxa-10-phosphaphenanthrene-10-oxide (DOPO) onto polydopamine (PDA) nanospheres via the bridging of silane coupling agent KH560. This additive exhibited two distinct degradation stages with low maximum degradation rates (1.79 and 1.52 %/min) and high charring ability (58.6 % at 700°C) under N 2 atmosphere. The EP composite containing 8 % PDA@KH560-DOPO achieved a limited oxygen index (LOI) of 31.8 % and a UL-94 V-0 rating, while maintaining good tensile and impact properties comparable to neat EP. The cone calorimeter test showed reductions in peak heat release rate (PHRR), total heat release (THR), and total smoke production (TSP) by 48.1, 32.1, and 19.0 % respectively. This is attributed to the cooperative flame-retarding mechanisms combining staged free-radical scavenging (phenoxy and P-containing radicals), inert gas dilution, and a reinforced char barrier (18.1 wt% in cone calorimeter test). Crucially, the composite also exhibited potent antibacterial activity, with over 94 % inhibition rate against Gram-positive bacteria (S. aureus). This work provides a practical pathway for expanding the applications of EP composites into domains that require fire-safe and hygienic standards.

Polymer materials commonly employed in low Earth orbit (LEO) environments are highly susceptible to atomic oxygen (AO) attack, leading to severe degradation and deterioration of their properties. To address this challenge, 3-glycidyloxypropyltrimethoxysilane-modified hexagonal boron nitride (h-BN@KH560) nanohybrids were synthesized and incorporated into epoxy (EP) composites to enhance their AO erosion resistance. The resulting hexagonal boron nitride-based epoxy nanocomposites (FBN/EP) were systematically evaluated for their tribological performance and AO erosion resistance using a series of characterization techniques. The results demonstrated that the incorporation of h-BN@KH560 nanohybrids significantly improved the wear resistance and AO erosion resistance of the EP matrix. Specifically, the FBN 1.0 /EP nanocomposite exhibited an 86.1% reduction in wear rate compared to pure EP, while FBN 5.0 /EP nanocomposite achieved optimal AO erosion resistance, with a minimal erosion rate of 3.58 × 10 –24 cm 3 atoms −1 at an AO dose of 1.2 × 10 21 atoms cm −2 . These findings indicate that the incorporating content-induced distribution of h-BN@KH560 within the EP matrix strongly influences the wear resistance of FBN/EP nanocomposites, but there is a relatively minor effect on their AO erosion resistance. The enhanced AO erosion resistance is attributed to the synergistic barrier protection provided by h-BN@KH560 and the formed B 2 O 3 and SiO 2 layers under AO irradiation. This study offers a promising strategy for extending the service life of epoxy nanocomposites in harsh LEO environments. Graphical abstract

Firstly, the bio-inspired polydopamine (PDA) was coated on the surface of carbon nitride (CN), then used it (CNP) as nano-dispersant to improve the dispersion of graphene (Gr) in water on the basis of π-π interaction. After that, the KH560 was further grafted on the CNPG surface to improve the compatibility between inorganic hybrids and epoxy resin . The results of large plate experiments showed that the backside temperature of composite IFR coating containing CNPG@Si hybrids was significantly lower than that of other samples. Meanwhile, its expansion height after furnace test reached the maximum value (17.8 mm), which was greatly improved compared with the pure epoxy coating. Further, the maximum thermal decomposition temperature and the amount of char residue for the CNPG@Si/EP sample were significantly enhanced through the TGA test result. Besides, CNPG@Si based sample showed the lowest smoke density rating (SDR) due to its excellent smoke suppression performance. From the analysis of the morphology and composition of the char layer for CNPG@Si based sample, it can be seen that the introduction of Gr and CN increased the compactness of the char layer, and silicon network structures remained in the char layer after combustion, which effectively increases its strength and heat insulation effect.

Despite the fact that PEDOT:PSS has been successfully used in the field of flexible electronics, some of its applications in the domain of rigid conductive coating have been limited by the pricey cost and subpar mechanical properties (hardness, adhesion, and moisture absorption) of the commercially available Clevios™ PH 1000, as well as the poor conductivity, film formation, and mechanical properties of the self-made PEDOT:PSS. In the process of investigating the low-cost preparation of PEDOT-based conductive polymer coatings, we discovered that self-made PEDOT:PSS, a waterborne epoxy resin, and a bio-based epoxy curing agent can be blended uniformly to produce good film-forming conductive coatings. Later, the addition of KH560-modified nano-SiO2further improved the coating’s hardness while ensuring a modest increase in conductivity. Meanwhile, the inadequacies of the epoxy resin, which are not UV-resistant, were considerably improved by the synergistic action of PEDOT:PSS and the modified SiO2. The result is a low-cost method designed for creating conductive coatings that are UV-resistant and may be utilized for electromagnetic, electrothermal, and antistatic shielding applications. Such a PEDOT:PSS/epoxy composite system and its design approach will broaden the scope of PEDOT:PSS’s application and will inspire future research in and practical implementations of PEDOT:PSS-based conducting coatings.Keywords:waterborne epoxy resin;PEDOT:PSS;high hardness;conductive coatings;bio-based;UV-resistant

In this study, a novel and multifunctional polyvinylidene fluoride-co-hexafluoropropyle (PVDF-HFP)/catechol-polyethyleneimine (CA-PEI)/Ag/3-glycidyloxy propyltrimethoxysilane (KH560) tubular nanofiber membrane (TNM) for applications in dye degradation and oil/water separation was fabricated. Firstly, the PVDF-HFP tubular nanofiber membranes were modified by using a mussel-inspired method. Then, Ag nanoparticles were assembled on the nanofiber surface to improve their excellent catalytic capacity for Methylene blue (MB) and Congo red (CR). Finally, the hydrophilic KH560 was grafted on nanofiber surface and the effects of KH560 concentration on the membrane performance were investigated. The results showed that when the KH560 concentration was 3 wt%, the modified membranes possessed a higher hydrophilicity and permeability. Meanwhile, it could also effectively separate various oil-in-water emulsions with high separation rate and separation efficiency at 0.02 MPa. Moreover, the catalytic and oil/water separation performances had no discernible decay after ten cycle tests, which promoted the potential application of modified PVDF-HFP TNMs for the treatment of practical oily wastewater.

Poly (vinylidene fluoride-co-hexafluoropropylene) (PVDF-HFP) polymer electrolytes suffer from low ionic strength and poor mechanical performance. Meanwhile, lithium lanthanum titanate (LLTO) fillers exhibit severe agglomeration and weak interfacial compatibility with the polymer matrix. To solve these problems, 3-glycidoxypropyltrimethoxysilane (KH560) at four different concentrations (1 wt%, 2 wt%, 3 wt%, 4 wt%) was loaded onto polydopamine-modified LLTO (PDA@LLTO). The modified materials were mixed with PVDF-HFP, and composite solid electrolytes were fabricated by the solution casting method. The epoxy groups in KH560 undergo ring-opening reactions with amino and hydroxyl moieties on PDA, while its trimethoxysilane groups crosslink with the polymer matrix, forming a robust “LLTO-PDA-KH560-polymer” interfacial structure. This dual modification markedly improves the dispersion of PDA@LLTO, strengthens interfacial adhesion, and enhances the mechanical and electrochemical properties of the composite electrolyte. All KH560 loadings suppress LLTO agglomeration, and the 3 wt% grafting ratio yields the optimal performance: a uniform and dense microstructure, a room-temperature ionic conductivity of 5.92 × 10 −4 S cm −1 , an electrochemical stability window extended to 4.88 V, and a tensile strength over 50% higher than the ungrafted sample. The modified electrolyte effectively inhibits lithium dendrite growth and enhances the cycling stability of solid-state batteries. This work demonstrates that KH560-PDA synergistic modification enables comprehensive performance optimization of composite electrolytes, offering a viable strategy for designing high-performance electrolytes for solid-state lithium-metal batteries.

The popular magnetic material of flaky carbonyl iron (FCI) is unfortunately vulnerable to electrochemical corrosion when exposed to a salty and foggy environment. This work reports on a sol-gel method that successfully modifies FCI particles, using lithium silicate (Li 2 SiO 3 ), poly dimethyl siloxane (PDMS), and γ-(2,3-epoxypropoxy) propytrimethoxysilane (KH560), to synthesize Fe@SiO 2 @KH560@PDMS hybrid composite, related to its organic–inorganic hybrid coatings. The favorable hydrophobicity of organic–inorganic hybrid coatings with the static contact angle of 120° impeded the contact between corrosive medium and FCI core. The results of electrochemical experiments also confirmed its excellent corrosion resistance , since the corrosion potential E corr was positively shifted to 0.01 V, and the corrosion current I corr was three orders of magnitude lower than that of the unmodified FCI particles. Thermogravimetric (TG) analysis indicates that the presence of hybrid coatings also improved the thermal stability of the produced material towards oxidation . Furthermore, the results of molecular dynamics simulation reveal that the hybrid layer inhibits the diffusion of corrosive medium.

Application of nanofiltration membranes in industries still has to contend with membrane fouling that causes a significant loss of separation performance. Herein, an innovative approach to design antifouling membranes with a narrowed pore size distribution by interfacial polymerization (IP) assisted by silane coupling agents is reported. An aqueous solution of piperazine anhydrous (PIP) and γ-(2,3-epoxypropoxy) propytrimethoxysilane (KH560) is employed to perform IP with an organic solution of trimesoyl chloride and tetraethyl orthosilicate (TEOS) on a porous support. In accordance with the results of molecular dynamics and dissipative particle dynamics simulations, the reactive additive KH560 accelerates the diffusion rate of PIP to enrich at the reaction boundary. Moreover, the hydrolysis/condensation of KH560 and TEOS at the aqueous/organic interface forms an interpenetrating network with the polyamide network, which regulates the separation layer structure. The characterization results indicate that the polyamide–silica membrane has a denser, thicker, and uniform separation layer. The mean pore size of the polyamide–silica membrane and the traditional polyamide membrane is 0.62 and 0.74 nm, respectively, and these correspond to the geometric standard deviation (namely, pore size distribution) of 1.39 and 1.97, respectively. It is proved that the narrower pore size distribution endows the polyamide–silica membrane with stronger antifouling performance (flux decay ratio decreases from 18.4 to 3.8%). Such a membrane also has impressive long-term antifouling stability during cane molasses decolorization at a high temperature (50 °C). The outcomes of this study not only provide a novel one-step multiple IP strategy to prepare antifouling nanofiltration membranes but also emphasize the importance of pore size distribution in fouling control for various industrial liquid separations.
