Developing intelligent antibacterial materials with environmental responsiveness is crucial for addressing the challenges of real-time monitoring and efficient infection control in the fields of wound healing and environmental remediation. In this study, a multifunctional Janus electrospun nanofibrous membrane based on a synergistic system of anthocyanin/thymol (AN/THY) was developed, which integrated unidirectional water transport, pH-responsive monitoring, antibacterial and antioxidant properties. Experimental results demonstrate that the Janus nanofibrous membrane exhibits excellent unidirectional water transport and inhibits reverse penetration due to the gradient pore structure and wettability difference between layers. It also exhibits a suitable physiological environment-compatible gas permeability of 14 mm/s, enabling efficient gas exchange. In addition, the bilayer membrane shows a DPPH radical scavenging rate of up to 91% and an antibacterial rate of nearly 100% against Escherichia coli and Staphylococcus aureus ; moreover, the membrane exhibits distinct color changes within the pH range of 3–13 and a high color reversibility of more than 95%. The developed Janus nanofibrous membrane has great potential in the fields of intelligent wound dressings, environmental monitoring, and provides a new strategy for the development of multifunctional intelligent materials.

Radiation protection products (RPP) that provide thermal insulation and radiation safety are crucial for personnel exposed to nuclear materials. Unfortunately, existing RPPs are unable to withstand the demands of high-temperature working environments, which severely limits their applications. In this work, flower-shaped Bi 2 O 3 (FBi 2 O 3 ) filled waterborne polyurethane (WPU) foam is proposed to address this challenge. The filling volume of this foam is relatively low, which makes it lightweight. Meanwhile, the compatibility of the interface between FBi 2 O 3 and WPU is improved by modifying the surface of the FBi 2 O 3 using titanate coupling agent (TCA). The uniform dispersion of FBi 2 O 3 enables the material to exhibit excellent x-ray shielding properties (94%–99%) and low thermal conductivity (0.033 W/(m K)). Experimental and simulation results indicate that the interaction between materials and x-rays increases collision probability and reduces secondary scattering. This study provides a viable approach for fabricating lightweight, thermally insulating RPP, opening new avenues for developing advanced RPP.

As a widely used general-purpose plastic, polyvinyl chloride (PVC) suffers from limited thermal stability, inherent brittleness, and a difficulty in balancing mechanical strength with toughness. To overcome these limitations, aramid nanomaterials (ANM)—formed through the self-assembly of poly(terephthaloylterephthalamide) (PPTA) molecules as the reinforcing phase—are directly constructed via an in situ synthesis (ISS) strategy in PVC/NMP and PVC/NMP/LiCl systems. Results demonstrate that this method achieves uniform dispersion and strong interfacial bonding of ANMs within the PVC matrix, significantly refining the composite microstructure. Compared with neat PVC, the PVC/ANM composites prepared by the ISS method showed a significant increase in both tensile strength and toughness, effectively breaking the conventional strength–toughness trade-off. In addition, these composites show enhanced thermal stability and flame retardancy, primarily due to strong interfacial interactions between the ANMs and the PVC matrix. This work not only confirms the great potential of the ISS strategy for preparing high-performance PVC composites but also provides a new technological pathway for addressing common strengthening and toughening challenges in polymer-matrix systems.

The nanoencapsulation of cypermethrin (CP) was carried out by miniemulsion polymerization, a convenient one-pot encapsulation technique for nanocapsules. The encapsulation was achieved by polymerization inducing phase separation within minidroplets dispersed in an aqueous phase. For nanocapsules prepared in this way, the type of surfactant and initiator, the level of the crosslinking agent or chain-transfer agent, and the monomer/CP ratio play a significant role in defining the end morphology of the latex particles. Specifically, for a styrene (St)/CP system, there were optimum levels of ionic surfactant (1.0 wt % sodium dodecyl sulfate), nonionic surfactant [0.5 wt % poly(ethylene glycol) monooctylphenyl ether], oil-soluble initiator [1.0 wt % azobis(isobutyronitrile)], crosslinking agent (1.0 wt % divinylbenzene), and a St/CP ratio of 1 : 1 for obtaining well-defined nanocapsules of CP. © 2012 Wiley Periodicals, Inc.

Electrolytic dehumidification with polymer electrolyte membranes (PEMs) is innovative as it enables portable, accurate, and efficient air dehumidification. However, during operation, the dehydration of the PEM results in a severe decrease in its dehumidification performance. In this study, for the purposes of improving the water retention, we developed two types of composite PEMs, Nafion Membrane 212 (N212)–SiO 2 and Nafion–SiO 2 . The hydration parameters (λ; H 2 O–SO 3 H) of N212–SiO 2 and Nafion–SiO 2 were increased by 20–61 and 40–92%, respectively, compared to that of Nafion 212. System experimental results show that in air with a 45% relative humidity, the dehumidification rates of N212–SiO 2 and Nafion–SiO 2 elements improved by 17 and 8%, respectively, and the respective increases in energy efficiency were 22 and 16%. In addition, the effect of the PEM water content on the dehumidification performance was more pronounced than those of other influencing factors such as the proton conduction resistance. The use of high-water-uptake PEMs positively helped optimize the electrolytic dehumidification, especially under low air humidities. © 2019 Wiley Periodicals, Inc. J. Appl. Polym.

Acrylic resin/micro-SiO 2 /polymethyl urea (AC/SiO 2 /PMU) composites were prepared by physical blends of acrylic resin latex (AC), polymethyl urea resin (PMU), and modified SiO 2 . The effects of SiO 2 and PMU content in the hybrid composites morphology and physical properties were investigated in detail using transmission electron microscopy (TEM), UV-Vis spectrometry (UV-Vis), scanning electron microscope (SEM), thermogravimetric analysis (TGA), and contact angle measurement. The results showed that introduction of SiO 2 into AC composites could increase the viscosity which caused by gelation and agglomeration of SiO 2 . The TEM, SEM images, and TGA results indicated that hybrid membranes have phase separation. During the film formation process, a high number of PMU and SiO 2 particles of an appropriate size were stranded on the surface of the film to form matting surface. These results highlight the sensitivity of the gloss to the polymer morphology and surface. © 2014 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2015 , 132 , 41707.

A series of thermoset oligoimides have been prepared by the thermal polycondensation of 1,4-bis(2,3-dicarboxyl-phenoxy)benzene dianhydride with three different aromatic diamines in the presence of 4-phenylethynylphthalic anhydride as an end capping reagent. The aromatic diamines included 4,4′-oxydianiline, 2,2′-bis(trifluoromethyl)benzidine (TFDB) and 2-phenyl-4,4′-diaminodiphenyl ether ( p -ODA). Effects of the chemical structures and molecular weights of the oligoimides on their aggregated structures, melt processability as well as the thermal and mechanical properties of the cured films were then systematically investigated. X-ray diffraction results indicated that ODA series oligoimides and TFDB series oligoimides showed crystallinity; however, the asymmetrical p -ODA enables the p -ODA series oligoimides to exhibit amorphous forms. So the p -ODA based oligoimides with molecular weight of 750 g mol −1 showed much lower melt viscosity at a low temperature and the melt viscosity could maintain below 1 Pa s −1 after isothermal aging for 2 h at any temperature in the range of 220–280 °C by rheological measurements. © 2019 Wiley Periodicals, Inc.

A novel polysulfone was easily synthesized by alternating copolymerization of norbornene with sulfur dioxide (SO 2 ) via free radical copolymerization and coordination copolymerization. Compared with other olefin derivatives, norbornene is a cyclic olefin having a larger steric hindrance, which is easily copolymerized with SO 2 , and the obtained poly(norbornene sulfone)s have excellent thermomechanical and optical properties. The effect of the different polymerization methods on the copolymerization reaction was analyzed in detail. The results suggested that different polymerization mechanisms exist in the different polymerization methods and affect the thermal stability and optical properties of the polysulfone. © 2016 Wiley Periodicals, Inc.

Small molecular plasticizers, widely used in flexible poly(vinyl chloride) (PVC), suffer from drawbacks including high migration rate and safety concerns. Low molecular weight polyesters are developed to address the challenges. In this contribution, adipic acid and 2-methyl-1,3-propanediol are used as monomers, and different monohydric alcohols are applied as capping agents to prepare symmetrically capped poly(2-methyl-1,3-propanediyl adipate) (PMPA) and asymmetrically capped poly(2-methyl-1,3-propanediyl adipate) (APMPA). The prepared PMPA and APMPA with different molecular weights are evaluated as PVC plasticizers. The results demonstrate that both PMPA and APMPA exhibit better plasticizing efficiency than that of common dioctyl phthalate (DOP). For instance, with 70 phr APMPA, PVC-APMPA3 (Using MPEG 600 g/mol as a capping agent) shows an elongation at break of 460% and a glass transition temperature ( T g ) of −19.1°C, along with significantly reduced migration loss (mass loss < 2% after 7-day immersed in petroleum ether). Furthermore, it presents an excellent hydrophilic durability, from about 24° decreases to 22° after immersed in water for 28 days. Notably, APMPA3, featuring asymmetrical α- and ω-end groups, not only demonstrates better plasticizing performance and low migration than that of DOP, but also offers the plasticized PVC an excellent and long-term hydrophilicity.

Low-emissivity and highly transparent coatings are of considerable interest for applications requiring simultaneous infrared radiation control and optical transparency. However, transparent polymer matrices typically exhibit relatively high intrinsic infrared emissivity, while the incorporation of low-emissivity fillers often leads to a loss of optical transparency, making it difficult to balance these properties. In this work, a highly transparent polyurethane (PU) matrix was prepared via a prepolymer method, and a multilayer PU/silver nanowire/PU (PU–AgNW–PU) composite coating was fabricated by introducing AgNWs to simultaneously regulate infrared emissivity and optical transmittance. The PU film (40 μm) exhibited an infrared emissivity of 0.65 (8–14 μm) at 80°C. After incorporation of AgNWs, the composite coating showed a reduced infrared emissivity of 0.45 while maintaining visible-light transmittance above 80% (400–700 nm) and haze below 20%. This multilayer structural design provides an effective strategy to balance low infrared emissivity and high optical transparency in PU-based coatings.

The design of flame retardant one-component epoxy resin (EP) with long pot life, low curing temperature and fast curing rate has been challenging in the industry. Herein, we synthesized a phosphate-containing imidazole fluid (TA) as the thermal latent curing agent of EP. Based on simple structural design, TA endows EP with excellent curing properties, storage properties, and flame retardant properties. According to DSC results, EP/TA systems exhibit low curing temperature and fast curing rate during operation. The rotary rheometer test confirms that the viscosity curve of EP/TA system maintains long-term stability at 40°C. The X-ray photoelectron spectroscopy (XPS) data reveals that TA releases imidazole intermediates and phosphorous compounds during curing. The former provides conditions for fast curing of EP, while the latter gives EP intrinsic flame retardant properties. With the addition of 20 wt.% TA, EP/TA-4 achieves UL-94 V-0 rating and 28.5% of LOI value. The study of flame retardant mechanism shows that the flame retardancy of TA mainly comes from the protective effect of phosphorus-rich char layer, the dilution effect of non-combustible gas and quenching effect of phosphorous compound. Besides, due to no solvent involved, the synthesis strategy of TA is environmentally friendly, showing a great potential of industrial application.

Developing dislysis membranes with outstanding hemocompatibility is the key of hemodialysis used for curing the kidney malfunction. Herein, polylactic acid (PLA) membrane with high water flux (640.2 L m −2 h −1 ) and bovine serum albumin (BSA) rejection (>97%) is prepared and subsequently modified by heparin-mimetic sulfonated graphene oxide (SGO) via modified mussel-inspired method. The (NH 4 ) 2 Fe(SO 4 ) 2 serves as Fenton catalyst significantly accelerates the oxidized polymerization of dopamine (DA) in DA- g -SGO to form polydopamine- g -SGO (PDA- g -SGO). The uniform immobilization of SGO significantly improves the hydrophilicity and electronegativity of the PLA membranes, inhibiting platelets adhesion. Moreover, the sulfonic group of SGO plays the role of anticoagulant as heparin. The obtained PLA/PDA- g -SGO membrane exhibits excellent hemocompatibility with longer recalcification time (230 s) and lower hemolysis ratio (1.6%) than those of original PLA membrane (120 s, 10.7%). This study demonstrates a potential way to improve the hemocompatibility of polymeric membranes.
