A new organic zinc heat stabilizer could be applied to polyvinyl chloride (PVC). Glutamic acid zinc complex (Glu-Zn) was synthesized by a simple precipitation method in one step under alkaline conditions using glutamic acid and zinc acetate dihydrate as reaction raw materials. Its chemical element composition of Zn 5 (C 5 H 7 NO 4 ) 2 (OH) 6 ·H 2 O was analyzed by elemental analysis, crucible thermogravimetric method, infrared spectroscopy, and thermogravimetric analysis. The heat stability effect of Glu-Zn in PVC was studied using Congo red and oven aging methods. The best synergistic thermal stabilization effect was achieved when Glu-Zn compounded with calcium stearate (CaSt 2 ) at a ratio of 0.6:2.4. Moreover, the heat stability mechanism of Glu-Zn in PVC was researched through experiments for the absorption of hydrogen chloride and substitution of unstable chlorine, and the results showed that Glu-Zn could substitute the active chlorine atoms in the PVC molecule to avert additional thermal degradation and also eliminate the acidic HCl generated by subsequent degradation. In addition, the commercial auxiliary heat stabilizers such as pentaerythritol (Pe), dibenzoyl methane (DBM), and epoxidized soybean oil (ESBO) were added to Glu-Zn/CaSt 2 to contrast their synergistic effects. The results showed that Pe had the best synergistic effect among the three additives.

Reversible photochromic behavior, enhanced through microstructural design, offers a robust strategy for next-generation anti-counterfeiting. In this study, high-resolution anti-counterfeiting labels were fabricated using melt electrowriting (MEW), a high-precision additive manufacturing technique. Poly( ε -caprolactone) (PCL) served as the polymer matrix and was incorporated with two photochromic dyes exhibiting distinct and reversible color transitions under UV/visible light irradiation. The chromatic contrast and fatigue resistance were quantitatively assessed by monitoring the total color difference (Δ E *), which exhibited negligible degradation even after over 500 switching cycles at high dye concentrations, confirming excellent reversibility and stability. Since stable jet formation is crucial for high-fidelity printing, the critical translation speed (CTS) and Taylor cone area variation were systematically analyzed to elucidate the influence of dye concentration on printability, and the mechanical properties of the printed scaffolds were concurrently evaluated. The results demonstrated that a 4 wt% dye loading achieved optimal jet stability and mechanical integrity. Moreover, by employing a dual-spinneret MEW system, a variety of complex, multicolor micro-patterns with both figurative and realistic features were successfully produced, significantly enhancing the difficulty of counterfeiting and broadening the applicability of MEW-based technologies in secure and intelligent labeling.

Lightweight, environmentally resistant electromagnetic shielding materials are critical for aerospace and military applications. Constructing multi-layer conductive network structure offers an effective pathway to achieve high-performance electromagnetic interference (EMI) shielding. In this work, we developed a lightweight fiber-reinforced composite paper that delivered ultra-high EMI shielding performance (SE) even under harsh conditions. A three-dimensional conductive network was formed by the controlled incorporation of Cu@PEEK fibers and carbon fibers (CFs) into a carbon nanotubes (CNTs)/PEEK fiber matrix. Experimental results revealed remarkable synergistic effects among the multi-scale fibers, endowing the composite paper with an exceptional EMI shielding effectiveness of 54.4 dB at an ultra-thin thickness of 0.3 mm (12 GHz). Furthermore, the stability of the EMI shielding performance was evaluated under extreme temperatures and near-infrared high-power laser irradiation. The composite paper retains over 80% of its shielding effectiveness, demonstrating the potential for application in complex environments. This work provides valuable insights for designing high-stability EMI shielding materials suited for extreme operational environments.

Epoxy resins (EPs) have gained increasing attention due to their excellent properties, but endowing EPs with high mechanical properties and migration resistance while maintaining flame retardancy remains a challenge. This study addresses this challenge by developing novel oligomeric flame retardants (PB-O and PB-E), synthesized via a Heck cross-coupling reaction of polybutadiene (PB) with decabromodiphenyl oxide (DBDPO) or decabromodiphenyl ethane (DBDPE). Differential scanning calorimetry (DSC) and thermogravimetric analysis (TGA) show these additives reduce EP curing temperatures and enhance char formation at elevated temperatures. UL-94 and microscale combustion calorimetry (MCC) tests confirm exceptional flame retardancy: composites with 5 phr PB-O/PB-E achieve V-1/V-0 ratings (vs. pure EP), with peak heat release rates (PHRR) reduced by 40.3%/40.0% for enhancing fire safety. Synergistic rigid-flexible effects (phenyl groups and PB chains) endow composites with outstanding mechanical properties: impact strength increases by 557% (PB-O)/524% (PB-E), flexural strength rises by 51.5%/49.2% versus unmodified EP. Migration rates of 5 phr PB-O/PB-E in EP composites show 0 after 84 h (5 phr PB@DBDPO/PB@DBDPE: 4.2%/4.0%) by migration tests. Hence, this work provides an integrated strategy to develop multifunctional oligomeric brominated flame retardants for EPs, which simultaneously improve flame retardancy, mechanical properties, and migration resistance to align with increasingly rigorous industrial requirements.

The growing demand for multifunctional polymers accelerates the development of materials integrating high strength, rapid self-healing, photoluminescence, and controlled biodegradability. In this work, a custom-designed naphthylimide-based hyperfluorescent compound (AHHN) with a rigid conjugated structure is incorporated as a chain extender into the matrix of a waterborne polyurethane (WPU). The obtained multifunctional WPU-AHHN simultaneously exhibits fluorescence, UV absorption, autonomous self-healing, and biodegradability. Abundant amide groups within AHHN serve as hydrogen-bond donors and acceptors, forming robust physical crosslinks with N, O, and H atoms in the polyurethane backbone. This hydrogen-bond network promotes microphase separation, significantly enhancing thermal stability, mechanical strength (tensile strength: 26.8 MPa), toughness, and extensibility (elongation at break: 1602%). Importantly, the hydrogen bond network enables efficient room-temperature self-healing, achieving 86.5% recovery after 15 h at 30°C. Furthermore, the synergistic utilization of petroleum-derived poly(ε-caprolactone) diol and bio-based castor oil provides tunable biodegradability, resulting in a weight loss of 4.56 wt.%–9.97 wt.% in a solution of lipase in phosphate-buffered saline after 4 weeks. Integrating high mechanical performance, self-healing capability, intrinsic fluorescence, and eco-degradability, WPU-AHHN demonstrates significant potential for emerging applications in optical anti-counterfeiting applications, flexible electronics, information encryption, and protective coatings.

Collagen coatings are widely used in the field of artificial blood vessels for improving the anti-bleeding and biocompatibility of vascular scaffolds, which has become a hotspot of international research. However, there has always been the challenge of poor interfacial compatibility between polyester, the artificial vascular material, and collagen, the natural biomaterial, with insufficient adhesion between the two, which can easily result in detachment and fail to meet the requirements for clinical use. To address the above problems, this study proposes to use the balloon dilatation technique, increasing the adhesion between the collagen and the vessel surface by pressurized treatment. The experimental results showed that textile blood vessels treated in a 37°C oven for 45 min were able to maintain the integrity and wettability of the collagen coating at a pressure of 5 atm. The pressurized treatment significantly increased the adhesion between the collagen and the textile vessel surface and effectively reduced the thickness of the collagen membrane, resulting in a significant increase in its densification. In conclusion, balloon dilatation and compression treatment is an effective technique to enhance the interfacial compatibility between collagen coatings and textile vessels and to reduce the risk of thrombosis, which has a broad application prospect.

Carbon quantum dots with the promising properties of small size, hydrophilicity, miscibility and dispersibility have raised considerable attention toward the fabrication of novel nanofiltration membranes, without affecting the structural integrity of the polyamide layer after the incorporation. In this study, the sulfonated carbon quantum dots (SCQDs) were added to the aqueous phase and then incorporated into the polyamide layer of the thin-film nanocomposite (TFN) membrane via the interfacial polymerization process. Compared to the pristine thin-film composite (TFC) membrane without the incorporation of CQDs (showing a nitrate rejection rate of 89.5% and permeation flux of 15.3 L m −2 h −1 ), the fabricated nanofiltration membrane with the incorporation of SCQDs (TFN-SCQDs) exhibits superior nitrate rejection (95.33%) and the permeation flux (39.2 L m −2 h −1 ) at the tested pressure of 0.6 MPa. The incorporation of SCQDs results in a 5.95% increase in nitrate rejection and the alluring enhancement in permeability up to 156.2%, thereby significantly overcoming the “trade-off” effect of the nanofiltration membrane. Additionally, the TFN-SCQDs membrane shows excellent properties of long-term operational stability, antioxidation and fouling resistance.

Rigid polyurethane foam (RPUF) is widely recognized as an ideal building material due to its low thermal conductivity and excellent compressive strength. However, achieving flame retardancy in RPUF typically requires high loadings of flame retardants, which can compromise the mechanical properties of the foam. In this study, a two-component waterborne flame-retardant coating (PA x ), composed of ammonium polyphosphate (APP) and polydopamine (PDA), is developed for the flame-retardant modification of RPUF. Experimental results indicate that surface modification with a minimal amount of PDA (1:75, mass ratio of PDA to APP) improves the dispersibility of APP in aqueous solution, resulting in a stable waterborne coating. With the aid of PDA mediated adhesion, APP firmly adheres to the surface of RPUF, forming a dense and stable flame-retardant layer. The PA x -coated foam (RPUF-PA 15 ) demonstrates excellent flame-retardant performance, achieving a limiting oxygen index (LOI) of 50.9% and meeting the UL-94 V-0 rating. Additionally, the compressive strength of RPUF-PA 15 (733.5 kPa) is 6.4% higher than pristine RPUF (689.3 kPa). In conclusion, an efficient waterborne flame-retardant coating has been successfully developed, achieving efficient flame retardancy for RPUF and providing a solid foundation for the development of such coatings.

Mosquitos are regarded as the deadliest animals in the world. Statistics show that they cause more harm to humans every year than all other animals combined, but only limited studies have been conducted on the modification for application in mosquito-repellent textiles up to now. To address the issues of low efficiency and high volatility caused by directly spraying mainstream commercial mosquito repellents on clothing and skin, a novel green synthetic route was proposed to graft icaridin onto modified alginate successfully in this study. FT-IR, XPS, MALDI-TOF MS, EA, and 13 C NMR confirm the successful grafting of icaridin onto the alginate backbone; then, the icaridin-grafted alginate derivatives with mosquito repellent properties were firmly loaded onto pp. nonwoven fabrics by Ca 2+ cross-linking for the first time, and the nonwovens obtained by this innovative method reached an 86.2% mosquito repellency rate. Additionally, through systematic exploration of the optimal mosquito-repellent ratio and coating thickness, we have developed a composite textile that efficiently repels mosquitoes, achieving a balance between air permeability (1982 mm/s) and moisture permeability (5376.678 g/m 2 ·24 h) while exhibiting excellent durability.

To solve the issues of single performance and insufficient durability of traditional functional textiles, in this study, an amino-enriched layer was constructed by co-deposition of polydopamine (PDA)/polyethyleneimine (PEI) on the fabric surface. Then, through the grafting of octadecylamine (ODA) and the in situ growth of zinc oxide nanoparticles, and finally, chlorination treatment was carried out to form N-chloramine active sites. A micro-nano composite superhydrophobic surface with antibacterial property was successfully constructed on the surface of cotton fabric. Scanning electron microscopy (SEM) and X-ray diffraction (XRD) characterization confirmed the in situ formation of ZnO particles on the fiber surface. The characteristic peaks in the X-ray photoelectron spectroscopy (XPS) spectrum verified the occurrence of Michael addition and Schiff base reactions among PDA/PEI/ODA. Performance tests demonstrated that the PDA/PEI/ODA/ZnO-Cotton-Cl composite exhibited a static water contact angle of 153° ± 2° and achieved a 87.8% ± 5.2% degradation rate to Methylene blue (MB) solution, and its antibacterial rate against both Escherichia coli ( E. coli ) and Staphylococcus aureus ( S. aureus ) reached 100%, indicating that this fabric had excellent antibacterial self-cleaning property. After 20 washing cycles, the fabric maintains high antibacterial efficacy and water repellency, demonstrating excellent durability. Additionally, it can be readily rechlorinated to restore its chlorine content. This material exhibits significant potential for medical protective equipment and outdoor applications, providing a novel approach to developing multifunctional textiles.

The preparation of epoxy resin (EP) with both excellent flame retardancy and mechanical properties is of great significance. In this study, a phosphorus/nitrogen/boron-containing reactive flame retardant, PBA, was successfully synthesized and incorporated into EP. The results indicate that PBA effectively enhances the fire resistance and suppresses smoke generation in EP. When the PBA loading was 6 wt%, the EP composites achieved a V-0 rating in the vertical burning test. The peak heat release rate and the total heat release decreased by 65.7% and 49.5%, respectively, while the peak smoke release rate and the total smoke release were reduced by 26.8% and 45.1%, respectively. Meanwhile, compared with pure EP samples, the EP samples containing 3 wt% PBA exhibited increases in tensile strength, elongation at break, and impact strength by approximately 12.2%, 31.5%, and 68.7%, respectively. This study provides an approach for preparing EP with a combination of flame-retardant and mechanical properties.

This study developed multifunctional fibrous membranes for wearable textiles. Using coaxial electrospinning, octadecane (Oct) was encapsulated within polylactic acid (PLA) to form core-shell PLA@Oct (P 1 ) fibers for thermal regulation. MXene was then sprayed onto P 1 to create a conductive layer (P 1 M) for electromagnetic interference (EMI) shielding. Finally, a waterproof layer of PLA/polyvinylidene fluoride (PVDF) blended with fluorinated SiO 2 was electrospun atop P 1 M, resulting in the multilayer membrane P 1 MP 2 . The optimized membrane demonstrated a high latent heat of 111.73 J/g, an effective EMI shielding effectiveness of 32.68 dB in the X-band, and a hydrophobic contact angle of 136.91°. This integration of temperature management, EMI shielding, and waterproof showcases certain potential for advanced wearable applications.
