In order to improve the mechanical properties and UV resistance of polylactic acid (PLA) composites, a bio-based additive (ESO-CUR) was synthesized by one-pot method. A new environment-friendly toughening agent was synthesized by using epoxy soybean oil (ESO) as the core material and curcumin (CUR) as the curing agent. PLA composite material with toughening and UV resistance was prepared by melt blending process. Among them, the elongation at break of 6%ESO-CUR/PLA reached 20.26% in the tensile test, which was 11.8 times higher than that of pure PLA. In addition, 6%ESO-CUR/PLA has excellent UV resistance, and the UV protection factor (UPF) is increased from 3.1 to 15,485 of pure PLA. The results show that the new environmental protection toughening agent has a significant synergistic effect on improving the mechanical properties and UV protection properties of PLA. In order to reduce the white pollution caused by traditional plastics, it provides a new way to prepare biodegradable materials with excellent properties.

The implementation of hot melt adhesives reaching structural adhesion with both impact resistance and detachability is of prospective industry value but still remains challenging. In this work, 2-amino-4-hydroxy-6-methylpyrimidine serving as both chain extender and end-capping reagent due to its isomerism, was developed to construct a supramolecular polyurethane-derived hot melt structural adhesive. The as-synthesized PUM elastomers occurs obvious decrease of molecular weight at 80°C compared to room temperature, revealing the existence of self-complementary 2-ureido-4[1H]-pyrimidinone (UPy) motifs at chain ends. This unique structure allows to chemically incorporate abundant hierarchical and quadruple hydrogen bonding moieties, which results in remarkable enhancement of shear strength, ranging from 6.4 to 16.6 MPa. More importantly, it also exhibits unique impact-strengthening and reproducible adhering ability. The Hopkinson-press-bar and cyclic tensile tests manifest that quadruple hydrogen bonds play a pivotal role in buffering external forces and increasing energy dissipation when exposed to high velocity impacts. The true stress and strain synchronously increase as the strain rate augments while the shear strength can even roar up to ~18 MPa at high tensile speed. With regard to mild synthetic conditions, atomic economic use of reactants, it is promising that this material has industrial potential to be utilized in applications referred to energy-absorption and reproducible structural adhesion.

The preparation of phase change materials (PCMs) with excellent heat storage capacity, shape stability, and working durability is of vital importance for their popularization and application. In this work, a series of form-stable PCMs was prepared via blending diglycidyl ether of bisphenol A (DGEBA), aliphatic anhydride with octadecyl side chains (MNAO), and paraffin together followed by thermal curing. Thanks to the plasticizing effect and self-assembly of paraffin, the crystalline behavior of paraffin and MNAO was hardly limited by the epoxy network, and the latent heat of EP/Pa-50 with 50 wt% paraffin content was high, up to 92.3 J/g. Meanwhile, EP/Pa-50 had a low supercooling extent of 11.0°C. Instead of the significant reduction in other properties of most PCMs after being blended with paraffin, the overall performance of EP/Pa-50 remained good due to the strong intermolecular interactions between paraffin and MNAO (based on their good compatibility) and the reliable epoxy network, and EP/Pa-50 exhibited excellent shape stability without the leakage problem, high thermal stability (remain stable below 170°C) and good mechanical properties (tensile strength up to 10.5 MPa). This work provides a facile strategy to prepare form-stable PCMs, which have promising application prospects in the field of thermal regulation.

Crude oil spills pose a significant pollution threat to the marine environment. Effective cleanup methods tailored for high-viscosity oil spills are essential. This study initially investigated the influence of pore size on the water and oil absorption capacities of reticulated polyurethane foam (PUF). Comparative experiments conducted with five distinct pore sizes ranging from 0.9 to 2.27 mm revealed that PUF with a pore size of 1.17 mm exhibited optimal adsorption performance for high-viscosity heavy oil (with an adsorption capacity of 38.0 g/g), albeit accompanied by a notable defect in water absorption (water absorption rate of 22.1 g/g). To address the poor hydrophobicity of the 1.17 mm PUF, modifications were introduced using polydopamine (PDA) and polyhedral oligomeric silsesquioxane (POSS) to develop a hydrophobic–oleophilic PUF@PDA-POSS composite material. The results indicated a 69.6% reduction in water absorption capacity for PUF@PDA-POSS compared to pure PUF (decreasing to 6.71 g/g), while the heavy oil adsorption capacity remained unchanged (at 39.1 g/g). After undergoing 10 adsorption–cleaning–regeneration cycles, PUF@PDA-POSS maintained over 90% of its initial adsorption performance, demonstrating excellent cyclic stability. This material combines high hydrophobicity, strong oil absorption capacity, environmental friendliness, and durability, thereby possessing significant application value in oil–water separation and marine oil spill remediation.

Fluorescent materials are extensively utilized in anti-counterfeiting and security applications, and surface cleanliness is crucial for preserving their functionality. This study presents a novel hydrophobic fluorescent coating characterized by a morphology in which particles are semi-embedded and evenly dispersed within the primer. The coating was developed using an innovative method that involves spraying hydrophobic silica onto a microscopically dissolved fluorescent polyethylene terephthalate (PET) primer. The coating demonstrates superior hydrophobicity, with a water contact angle (WCA) of 165.0° ± 5.0° and a sliding angle of 3.0°, as well as an outstanding luminous intensity 541.4 mcd/m 2 . Due to strong primer and semi-embedded particle binding, the coating shows good durability. After 80 wear treatment, the hydrophobic properties of the fluorescent coating were largely maintained. After 32 days of exposure to 0.68 W/m 2 ultraviolet light, the contact angle decreased from 160.0° to 154.7° (with a sliding angle of 8.0°). In addition, the firmness, transparency, and self-cleaning function of the coating can be effectively maintained. The coating in this work has solved the inherent problems of functionality, hydrophobicity, and durability in the coating field, and has a wide range of applications including flexible fabrics, road safety field, and building exterior materials.

In the application of waterborne coatings, enhancing the water resistance and mechanical properties of coating films derived from waterborne coatings has been a critical challenge in need of urgent resolution. To tackle this issue, we propose an innovative strategy that involves surface modification of cellulose nanocrystals (CNC) using long-chain alkyl alcohols and the preparation of polyurethane composite films with excellent hydrophobicity by compounding the modified CNC (C-CNC) with waterborne polyurethane (WPU). Using a custom mold, we achieved surface hydrophobic functionalization. This study delves into the impact of CNC on the hydrophobic composite film, particularly focusing on its contribution to film morphology, thermal properties, and mechanical properties, significantly enhancing its hydrophobicity. Experimental results demonstrate that the mold with a rough surface constructs numerous rough and porous structures on the coating film surface, significantly enhancing its hydrophobicity. Notably, the C 28 –CNC/WPU composite film prepared using octacosanol-modified CNC exhibits the best hydrophobicity, with a water contact angle reaching 122.80°. This strategy of preparing hydrophobic coating films through a simple and effective method not only overcomes limitations of waterborne coatings in terms of water resistance and mechanical properties but also holds significant potential for environmentally friendly coatings, offering new insights for waterborne coating development.

To enhance the stability of epoxy (EP) coatings on steel bars while improving their active and passive corrosion protection properties, the functional composite coatings were designed and prepared. Intercalated zirconium phosphate nanofillers (LCZrP) loaded with corrosion inhibitors were firstly synthesized and designed, and then were integrated into silane coatings (SC), which were preapplied to the bar substrate to enhance the integrity and interfacial adhesion properties. Lastly, an epoxy layer was applied, resulting in the functional composite coatings (LCZrP/SC/EP). The chemical composition and surface morphology were performed using scanning electron microscopy–energy dispersive X-ray spectroscopy (SEM-EDS). The corrosion resistance of the coatings was evaluated using electrochemical impedance spectroscopy (EIS), complemented by adhesion tests to analyze the service stability of the coatings. The findings revealed that the silane interlayer notably improved the interfacial bonding at the junction where the epoxy resin interacts with the steel bar, thereby enhancing the corrosion resistance. Notably, the coating presented the optimal corrosion resistance when the nanofiller content was 0.04 wt.%. The impedance modulus at 0.01 Hz (|Z| 0.01Hz ) for the LCZrP/SC/EP coated coating was 5.05 × 10 10 Ω·cm 2 , which was two orders of magnitude greater than that of the EP coatings and the EP coating with silane interlayer (SC/EP) by one order of magnitude. Following 30 days of immersion, its |Z| 0 . 01Hz remained higher than the EP coating as well as the SC/EP coatings. The integral LCZrP/SC/EP coatings exhibit excellent long-lasting corrosion protection, owing to the self-responsive characteristics of LCZrP, the interfacial adhesion of the LCZrP/SC interlayer, and the enhanced barrier effect of the EP coatings. This combination effectively integrates active and passive protection strategies, thereby preventing metal corrosion. The above solution ensures that the coatings provide durable and reliable protection against corrosion over extended periods.

In the era of high-frequency 5G technology, the exigency for copper clad laminate (CCL) substrate materials of unparalleled performance has grown exponentially. These materials necessitate possessing not only a diminutive dielectric constant, elevated thermal stability, and robust mechanical properties but also an inherent flame-retardant nature to ensure utmost safety and unwavering stability. However, conventional phosphorus-based epoxy systems, erstwhile employed as CCL substrate materials, have proven inadequate in meeting the demands of high-performance applications. Consequently, the development of novel phosphorus-based flame-retardant systems has become an imperative pursuit. In this study, we synthesized a series of flame-retardant cured resins by incorporating octavinyloctasilasesquioxane ((vinyl) 8 -POSS) and DVSBCB prepolymers (pDVSBCB) into three different BCB functionalized phosphorus-containing monomers (Ph 2 POB, PhPOB 2 , and POB 3 ), followed by thermal curing. Among these cured resins, POB 3 /BCBNPs/(vinyl) 8 -POSS/pDVSBCB (M4) exhibits remarkable properties, including an extremely low dielectric constant ( D k : 2.53) and dielectric loss ( D f : 2.09 × 10 −3 ), excellent thermal stability with a T 5% value of 451°C, a coefficient of thermal expansion (CTE) of 19.94 ppm/°C over the temperature range of 30°C–300°C, a high thermal release (THR) value of 31.6 kJ/g, and superior mechanical characteristics, such as an elastic modulus of 22.96 GPa and a remarkable hardness of 1.46 GPa. These exceptional properties position M4 as a promising candidate for the development of advanced CCL substrate materials.

Polyurethane elastomer (PUE) is extensively used for impact protection owing to commendable strength and toughness. However, PUE suffers from insufficient energy absorption and easy cracking under high-speed impact. Herein, hybrid nanomaterials (MMT/CNTs), formed by combining functionalized carbon nanotubes (CNTs) and organically modified montmorillonite (MMT) through ionic bonding, were incorporated into PUE, which enhances the impact resistance significantly under high-speed conditions. The enhancement of the impact resistance of the PUE composites was ascribed to the hybridization of CNTs and MMT, which facilitated the dispersion of each other in the matrix. Meanwhile, the CNTs anchored in the MMT interlayer can effectively support the interlayer space and promote internal stress and heat transfer. The results revealed that incorporating CNTs expanded MMT's interlayer spacing to 3.84 nm. Compared to pure PUE, the composites containing 2 wt% MMT/CNTs showed an increase in compressive strength, modulus of elasticity, dynamic compressive strength, and energy absorption by 61.0%, 111.6%, 73.8%, and 49.0%, respectively. This work shows that the PUE-MMT/CNTs is expected to be used as a high-performance impact-resistant material in aerospace, military defense, and other high-speed impact fields.

In this paper, a starch-based flocculant (ADSt) with medium and low temperature solubility and enhanced flocculation effect was synthesized using corn starch, acrylamide, and dimethyldiallyl ammonium chloride as main materials by the ethanol-alkali method and grafting method. The main mechanism of ADSt's flocculation was electrical neutralization and bridging. The flocculation performance of ADSt was verified by using it along with polymeric aluminum chloride (PAC) as coagulant/flocculant, dispersible dye (dispersible yellow RGFL), and reactive dye (active trimeric blue KN-G) to simulate dye wastewater. For the dispersed yellow water sample and active emerald blue water sample, the dosage of PAC was 40 and 35 mg/L respectively. When the dosage of ADSt was 10 mg/L with a dye content of 100 mg/L, the decolorization rates for both dyes reached up to 96.2% and 94.4% respectively. The properties of the flocs such as size and two-dimensional fractal structure were described. The prepared ADSt maintained a good flocculation effect in the pH range of 5–9 due to its excellent water solubility achieved through the ethanol-alkali preparation process, where its solubility reached 86.7% at 30°C. Overall, the preparation process for ADSt is simple, cost-effective, while providing an effective solution for treating printing and dyeing wastewater.

A portable home hemodialysis device is a miniaturized and easy-to-operate medical apparatus designed for patients with chronic kidney disease, enabling them to conveniently perform hemodialysis at home or while traveling. However, it imposes high requirements on the dialysis membrane in terms of dialysis efficiency, adsorption capacity, and blood compatibility. In this study, the composite membrane was fabricated through electrospinning, which is an in situ synthesis of carbon nano tube (CNT) bridged UiO 66 (COOH) 2 on PTFE fibers. UiO 66 (COOH) 2 increased the adsorption site by association with CNT, and achieved the adsorption of creatinine by hydrogen bond and π bond, which greatly reduced the usage of dialysis solution. UiO 66 (COOH) 2 and CNT were first combined for creatinine adsorption, and its maximum static adsorption capacity was 66 mg/g. During the dialysis, the yielding membrane showed a creatinine clearance of 64.89% and a resistance protein rate of more than 98%. Compared with pure PTFE dialysis membrane, the amount of dialysate used to achieve the same dialysis effect was merely 1/10. Furthermore, the membrane has a hemolysis rate of 2% and a low platelet adhesion rate, which shows excellent blood compatibility. Therefore, the dialysis membrane prepared in this study is expected to promote the development of portable home hemodialysis devices.

Epoxy resin is widely used in fiber-reinforced composite structures, but its application in high-end projects is limited due to the relatively brittle characteristics caused by its high crosslink density. In this paper, the reaction process of ZnO surface treated with silane coupling agent is described, and the toughening mechanism of nano-ZnO on resin matrix is elaborated. A three-level three-factor experimental strategy has been designed, and orthogonal experimental tests were conducted to investigate the influence of different design parameters, such as solid–liquid epoxy resin ratio (SLR), mass contents of nano-ZnO and catalytic agent (2E4MI). With the results of three-point bending (3P-bending) tests and hardness tests of the beams prepared with twill woven fabrics, surface response analysis based on statistics was carried out to evaluate and optimize design parameters. Results show that, for the beam with the optimized configuration, the maximum bending load, bending stiffness, and hardness were increased by 40.02%, 51.25%, and 58.18%, respectively.
