This paper described the synthesis of copolymer emulsions of fluorine and siloxane-containing acrylates for water-repellent cotton fabrics coatings. Chemical composition, morphology structure, and properties of the latex copolymers were investigated by Fourier transform infrared (FTIR), dynamic light scattering (DLS), gel permeation chromatography (GPC), and transmission electron microscopy (TEM), thermogravimetric analysis (TGA), and scanning electron microscopy (SEM). Effects of water-repellent functional monomers (R f ) on surface morphology, water contact angle, and water-repellent properties of the coated fabric surface were also studied. The results indicated that R f greatly influenced molecular mass distribution of the latex copolymers, the molecular aggregation states and orientation of R f on the coated fabric surface, and water-repellency of coated cotton fabrics.

This work presents the synthesis of a high-silicon organosilicon-modified epoxy resin via ester exchange reaction. The resulting coating successfully combines the advantageous properties of its constituents, demonstrating excellent strength and toughness even at silicon contents exceeding 30%. Specifically, the tensile strength and elongation at break were enhanced by 35.91% and 61.77%, respectively, compared to the unmodified epoxy resin. The uniformly dispersed organosilicon not only improved the thermal stability of the matrix but also, through slight enrichment at the coating surface, conferred enhanced hydrophobic characteristics. Under prolonged exposure to acidic and saline corrosive environments, the in situ enriched silica layer effectively prevents the diffusion of corrosive media, thereby significantly enhancing the coating's corrosion resistance. The mechanism underlying the coating's performance and its degradation was systematically investigated using scanning electron microscopy (SEM), thermogravimetric analysis (TGA), dynamic mechanical analysis (DMA), and electrochemical impedance spectroscopy (EIS). This convenient and efficient preparation method offers a novel strategy for corrosion protection in metal pipeline engineering.

In the current field of medical research, oxidative stress-induced damage to the body has become a significant contributor to the development of many diseases and has garnered extensive attention from the academic community. Reactive oxygen species (ROS), as key mediators in the process of oxidative stress, can cause severe damage to body tissues when their excessive accumulation occurs. Therefore, exploring efficient antioxidant strategies has become an urgent task in medical and scientific research. Currently, numerous. Studies have shown that selenium nanoparticles (SeNPs) can efficiently scavenge excessive ROS in the body, demonstrating great application potential in the field of antioxidant therapy. At the same time, the in situ thermosensitive hydrogel drug delivery system has gradually occupied an important position in the field of drug delivery due to its thermosensitivity and injectability. Based on the above research results, we have developed an innovative in situ injectable thermosensitive hydrogel system—F127/HA-SeNPs. This system combines F127 and hyaluronic acid as stable and efficient carriers, successfully loading SeNPs with strong antioxidant efficacy. This hydrogel exhibits thermosensitivity, injectability, adhesiveness, excellent biocompatibility, and antioxidant properties. Most importantly, relying on the loaded SeNPs, this hydrogel system exhibits a powerful and continuously stable ROS scavenging ability, effectively protecting cells from oxidative stress damage and improving mitochondrial dysfunction, thereby providing a practical and highly promising treatment solution for oxidative stress-related diseases. Its material properties and functional mechanisms endow it with good application value and development prospects during the process of disease intervention.

In this paper, an efficient flame retardant, 9,10-dihydro-9-oxa-10-phosphaphenanthrene-10-oxide (DOPO) was covalently grafted onto the surface of expandable graphite (EG). The resultant DOPO-grafted expandable graphite (EG-g-DOPO) was characterized by Fourier transform infrared spectroscopy, energy dispersive spectroscopy, and X-ray photoelectron spectroscopy (XPS), respectively. The thermal stability of EG-g-DOPO was also evaluated by thermogravimetric analysis (TGA). Moreover, a series of flame-retardant ultra-high-molecular-weight polyethylene (UHMWPE) composites with various concentrations of EG-g-DOPO were prepared and evaluated. The results show that the UHMWPE composite with 20 wt% EG-g-DOPO possesses a satisfactory UL-94 flame-retardant grade (V-0) and a high limiting oxygen index (30.6%). The residual char of the UHMWPE composite with higher EG-g-DOPO concentration shows more compact and integrated, providing an efficient barrier for heat release.

Self-healing property is an excellent feature that can improve the reliability and durability of the materials. In this study, carboxylic multi-walled carbon nanotubes (S-CNTs) and 2,2′-dithiodibenzoic acid (DTSA) were introduced into epoxidized natural rubber (ENR) to prepare a self-healing rubber. S-CNTs and DTSA could react with epoxy groups of ENR to effectively cross-link ENR, in which the cross-linked network consisted of reversible disulfide bonds, β-hydroxyl ester bonds, and hydrogen bonds. The reconfigurable cross-linked network endowed the ENR/S-CNTs/DTSA composites with great self-healing behavior with efficiency up to 99.7%. The multiple cross-linked networks also enhanced the mechanical properties of the composite, whose tensile strength reached more than 400% of the neat ENR. Additionally, optical microscope and scanning electron microscopy disclosed the evolution of the damaged area during the self-healing process, and the crack could be completely repaired after the healing process. This work provides an effective and concise method to prepare self-healing ENR-based elastomer, and it may expand the research scope of self-healing materials.

Recently, silicone rubber (VMQ) was extensively used in household articles and medical devices. To develop a kind of safe and long-term antimicrobial VMQ was of great significance. In this work, a kind of vinyl-contained polyhexamethylene guanidine hydrochloride (VPHMG) was synthesized and used as antimicrobial additive for VMQ. With the increasing of VPHMG addition, the mechanical properties and antimicrobial properties of VMQ-VPHMG were significantly improved. In particular, the antimicrobial rates against Escherichia coli and Staphylococcus aureus were higher than 99.99% as for 4 wt% of VPHMG addition. Moreover, the surface concentration of VPHMG as well as the antimicrobial rates revealed almost unchanged after being extracted by water and methanol. All the results indicated the vinyl-contained VPHMG vulcanization and therefore provided the permanent antimicrobial performance for VMQ.

The nanocomposites (NCs) of cross-linked polyaniline (CPA) with a variety of carbon nanomaterials (CNMs) (CPA/CNMs NCs) was prepared by the chemical oxidative copolymerization of PANI and p-phenylenediamine (PPDA) with triphenylamine (TPA) in the presence of CNMs. The results of XRD, FTIR and Raman indicated that the CPA/CNMs NCs were effectively synthesized with strong interactions among the constituents. The morphology study demonstrated that CNMs were well coated by CPA and produce a well-aligned nanorod core-shell structure with the large surface area which may be more beneficial to electrical conductivity when used as electrode materials. Differential thermal analysis techniques (TGA-DTG) were used to characterize the thermal stability of NCs. The heat of formation of CPA monomer from TPA, PPDA and aniline (ANI) were computed using Density Functional Theory (DFT) calculations. The NCs of G-MWCNTs demonstrate higher affinity to oxidation of Chlorophenols (CPHs) than glassy carbon electrode (GCE), CPA/GCE and the other NCs. Differential pulse voltammetry (DPV) was used for the trace determination of 2,4-dichlorophenol (2,4-DCP). Under the optimum conditions, the peak current of 2,4-DCP was proportional to its concentration in the range of 0.05-0.6 μmol/L. The detection limit was 7.6 nmol/L. The method was successfully applied for the determination of 2,4-DCP in fish farm water with satisfactory recoveries. The suggested method has an advantage to be used for water samples due to its short analytical time, rapid response, high sensitivity, and excellent selectivity with good reproducibility.

In order to obtain a loose selective layer of NFC membranes for dye desalination, a novel polyesteramide composite nanofiltration membrane based on Galp/PIP was fabricated by interfacial polymerization (IP) with d -(+)-galactose (Galp) and piperazine (PIP) as the alcoholic hydroxyl-amino mixed aqueous monomer and trimesoyl chloride (TMC) as the organic monomer in this work. The influence of the Galp/PIP weight ratio on the membrane's properties and separation performance was systematically investigated. The results indicate that the water flux and dye wastewater flux, the thickness of the selective layer, surface roughness, molecular weight cutoff (MWCO), and average pore size increased; however, the surface zeta potential became less negative due to the neutral charge of Galp, and the water contact angle decreased with the increase of the Galp/PIP. The water permeance and dye rejection were strongly dependent on the Galp/PIP ratio. At the optimal ratio of 4/6, the water permeation and the dye wastewater flux were up to 19.7 and 13.8 L/m 2 h bar, respectively, and the RB5 rejection was 92%. Compared to 0/10, the water permeation and the dye wastewater flux increased 59.2% and 57.5%, respectively, and the RB5 rejection was 97.4%, while the NaCl rejection was below 5%. In addition, this outstanding fractionation performance remained stable during extended operation with simulated dye/salt wastewater.

Polyurethane as a high-performance polymer material characterized by high toughness, corrosion resistance, and good wear resistance can be widely used in bearing applications. However, under water-lubricated conditions, the inherently weak hydrophilicity of polyurethane surfaces limits the formation of a stable hydrated lubrication layer, thereby restricting their tribological performance. To overcome this limitation, sulfonate groups-containing polyurethane ionomers were synthesized via condensation polymerization, endowing the material surface with a negative charge. Specifically, the sulfonic acid group can adsorb hydrated cations through electrostatic action to form a hydrated lubrication film on the surface, which can effectively improve the material's tribological performance. The friction coefficients of polyurethane ionomer with TBAB-BES molar ratio of 3% (PUI-3) were significantly reduced when a 3 wt% NaCl solution was used as the lubricant. When the sliding speed was 0.01 m/s, the coefficient of friction for PUI-3 was 0.053, achieving a 60% reduction in friction coefficient. Furthermore, the PUI-3 with SO 3 − exhibited both excellent mechanical properties and water resistance. This work provides a new approach to improving the tribological properties of polyurethane materials in marine environments.

Effective heat dissipation and electrical insulation are urgently required for filling materials of cable joints. Herein, we construct a thermally conductive and electrically insulating hybrid network consisting of aluminum oxide (Al 2 O 3 ) and boron nitride (BN) in polyurethane (PU)-based filling materials to meliorate the heat transfer ability for improved heat dissipation of cable joints. The resultant Al 2 O 3 /BN/PU composite displays an excellent thermal conductivity of 0.96 W/(m·K), outperforming Al 2 O 3 /PU composites by 84% at the total filler content of 25 wt%. The synergistic improvement of thermally conductive properties is ascribed to the fact that BN sheets bridge the gap among spherical Al 2 O 3 to form a large contact area for rapid phonon transmission. Infrared thermal images further demonstrate that the hybrid Al 2 O 3 /BN/PU composite has a stronger capacity to remove heat compared with the single Al 2 O 3 /PU composite. The electrical insulation, high mechanical strength, and thermal stability are also gathered. Our work paves a valuable way for designing and fabricating high-performance thermally conductive filling materials for effective cable joint cooling.

Polyamide 6 (PA6) composites offer great promise for industrial applications, yet balancing flame retardancy with mechanical properties is an ongoing challenge. Epoxy silicone oil (ESO) acted as a reactive compatibilizer to prepare flame-retardant PA6/ADP/ESO composites. The fire safety of composites was evaluated using standard flame-retardant tests and combustion behavior tests. Meanwhile, the effects of ESO incorporation on the rheological behavior, mechanical properties, and thermal stability of PA6/ADP composites were systematically studied by rheological tests, impact tests, and thermogravimetric analysis (TGA). The results showed that even with a total addition of only 11% of the ADP/ESO (96:4) system, the PA6 composites still passed the UL-94 V-0 rating with a limiting oxygen index (LOI) of 30.7%. Compared to the pure PA6/ADP system, the PA6/ADP/ESO composites had a 43.11% lower peak of smoke production rate (PSPR) and excellent fire resistance. Furthermore, the impact strength of the PA6/ADP 96 ESO 4 composites was significantly improved, which was attributed to the chemical reaction between the epoxy functionalities in ESO and the terminal groups of PA6 chains, thereby promoting chain extension and the establishment of cross-linked networks. Meanwhile, the melt viscosity of the system also increased. Interestingly, the increased shear force exerted by the matrix on the ADP aggregates not only significantly improved the dispersibility of ADP within the matrix but also helped to alleviate stress concentration. A simple, effective method produces high-performance PA6 composites that balance flame retardancy with mechanical integrity.
