Flame-retardant fabrics require both washing durability and skin affinity. However, their development faces significant challenges due to the weak interaction between flame retardants and fabrics, and the generally high mass loading needed to achieve effective flame retardancy. Herein, we developed halogen- and formaldehyde-free flame-retardant wool/nylon (W/N) fabric through covalent grafting of bio-resourced pyridoxal phosphate (PP). The grafting achieved a very low weight gain of 3.3%, yet the resulting W/N-PP fabric exhibited a high limiting oxygen index (LOI) of 31.3%, corresponding to an 18.1% increase over pristine W/N fabric. Meanwhile, the peak heat release rate (PHRR) and total heat release (THR) of the obtained W/N-PP were reduced by 46.4% and 17.2%, respectively. Benefiting from the covalent linkage established via the Schiff base reaction between PP and the W/N fabric, the W/N-PP demonstrates superior washing durability. After 24 h of washing, the flame-retardant performance of W/N-PP was retained. Moreover, W/N-PP also retains the outstanding mechanical properties of pure W/N fabric. This facile and environmental process provided a powerful basis for technology and potential industrial applications.

This study pioneers the grafting of oleylamine onto halloysite nanotubes (HNTs) to synthesize a low-temperature composite modifying agent for rubber (HNTs-Y). It enables the synergistic regulation of the low-temperature performance of nitrile butadiene rubber (NBR) via a “plasticization-reinforcement” mechanism, addressing both the migration propensity of conventional small-molecule plasticizers and the insufficient low-temperature modification efficacy of pristine HNTs. This work thereby provides a novel multifunctional modification strategy for optimizing the low-temperature performance of elastomers. Experimental results demonstrate that HNTs-Y significantly enhances the low-temperature resistance of NBR. Specifically, at a loading of 6 phr, the hardness difference of 4 # NBR between −40°C and 40°C is reduced by 45.2% compared to 1 # NBR, indicating improved hardness stability over a broad temperature range. Additionally, the tensile strength of 4 # NBR at −20°C is 79% higher than that at 20°C and 77% higher than that of 1 # NBR, reflecting enhanced resistance to tensile fracture under low-temperature conditions. Furthermore, with the increase in HNTs-Y content, the brittle temperature ( T b ) and glass transition temperature ( T g ) of NBR exhibit an overall downward trend. For 4 # NBR, the T b reaches −52°C and the T g is −29.5°C, manifesting excellent low-temperature resistance.

This study reports the development of ethanol-selective composite membranes for pervaporation (PV) based on polydimethylsiloxane (PDMS) embedded with reduced graphene oxide@silica core-shell (GSCS) particles. To enhance interfacial compatibility and particle dispersion within the matrix, 1H,1H,2H,2H-perfluorodecyltriethoxysilane (FDTS) was immobilized onto the GSCS to entangle with PDMS chains. A pre-polymerization strategy was adopted to increase the viscosity of the casting suspension, facilitating higher filler loading and improved ethanol separation performance. Optimal separation performance was achieved with a casting solution viscosity of 4 Pa s, yielding a maximum selectivity of 3.94. The scanning electron microscope (SEM) confirmed the formation of smooth defect-free PDMS/FDTS-GSCS composite membranes. The PV testing of these membranes demonstrated a high separation factor of 11.03 and a permeation flux of 242 g m −2 h −1 for separating a 10 wt% ethanol/water mixture at 40°C. Critically, the composite membranes exhibited excellent operational stability over a continuous 168-h test period. These findings indicate that incorporating FDTS-modified GSCS into PDMS significantly enhances ethanol selectivity, highlighting the potential of these membranes for bioethanol recovery applications.

Advances in electronic device miniaturization and system integration, alongside rapid progress in wireless communication technologies, have significantly amplified electromagnetic interference problems. This development necessitates the creation of high-performance electromagnetic shielding materials. This study presents a new design for electromagnetic shielding composites comprising an asymmetric structure of cobalt-coated nylon 6 microspheres (PA6@Co), silver nanowires (AgNWs) and poly(vinylidene fluoride) (PVDF). Specifically, PA6 microspheres were prepared using anionic reaction-induced phase separation, and cobalt was plated on their surfaces, thereby forming magnetic PA6@Co microspheres. The magnetic saturation intensity of these microspheres can reach 80 emu/g. The asymmetric PA6@Co/AgNWs/PVDF electromagnetic shielding composites with absorption-dominant characteristics were constructed using AgNWs as the conductive filler and PVDF as the matrix. The results show that within the X-band (8.2–12.4 GHz) range, the PA6@Co/AgNWs/PVDF composite material exhibits excellent electromagnetic shielding performance. Its maximum electromagnetic shielding efficiency (SET) reaches 48.1 dB, and the absorption coefficient (A) is 0.8, demonstrating a distinct absorption-dominant shielding characteristic. This asymmetric structural design strategy solves the limitations of traditional shielding materials and provides a new approach to developing environmentally friendly, efficient electromagnetic shielding materials.

Conductive hydrogels are promising for flexible wearable sensors due to their flexibility, conductivity, and sensing capabilities. Herein, a multifunctional polyvinyl alcohol/4-carboxyphenylboronic acid/carboxymethyl cellulose@polyaniline hydrogel is fabricated by embedding spherical carboxymethyl cellulose@polyaniline microspheres into a PVA/4-carboxyphenylboronic acid hydrogel. The synergistic effect of borate and hydrogen bonds forms a dynamic dual-crosslinking network, endowing the hydrogel with high tensile strength (0.31 MPa), excellent stretchability (1415%), fast self-healing ability, and good conductivity (3.57 S m −1 ). Notably, the engineered hydrogel is assembled as a dual-responsive sensor, exhibiting strain and temperature sensing for wearable electronics and healthcare monitoring applications. As a strain sensor, it showed good sensitivity (gauge factor: 1.88), fast response/recovery time (about 200 ms), and cyclic stability, allowing accurate detection of joint movements and facial expressions. As a temperature sensor, its temperature-sensing capability relies on the synergistic effect of the dynamic rearrangement of borate (B O C) bonds and hydrogen bonds, PANI's temperature-dependent conductivity, and ionic mobility. Thus, it exhibits a negative temperature coefficient of resistance (TCR = −1.52%/°C) in the temperature range of 20°C–60°C, enabling continuous body temperature monitoring and detection of febrile states. This work provides a general strategy for self-healing dual-responsive sensor hydrogels for wearable electronics in healthcare and human-robot interfaces.

Fast UV-cured Polybutadiene films were prepared in 10 s by using mercaptan pentaerythritol tetra(3-mercaptopropionate) (PETMP) as the cross-linker and PETMP-treated nano-SiO 2 as the filler, achieving significant improvements in overall performance, which may be applied as insulating materials for flexible printed circuits. The dispersion of SiO 2 in the polymer matrix was improved after treatment by PETMP and served as a “hard core” in enhancing their hardness greatly and improving the tensile strength about 50% from 7.5 to 15.2 MPa; they still retain excellent flexibility, maintaining shapes without cracking and peeling while folding in half under squeezing. The thermal expansion coefficient decreased from 2.22 × 10 −4 /°C to 2.02 × 10 −4 /°C and the glass transition temperature rose from 47.50°C to 58.62°C; meanwhile, they exhibited higher decomposing temperatures and higher residues, indicating the stabilizing effect of nano fillers. The incorporation of SiO 2 decreased their dielectric constant from 3.12 to 2.94 while maintaining stable dielectric loss of less than 0.02. Moreover, the addition of pretreated SiO 2 also improved their resistance to pure and salt water. Nevertheless, the excessive addition of SiO 2 led to local aggregations and thus adversely affected their overall properties if its addition was above 8% as seen from SEM pictures.

A dual-surfactant modification strategy was developed to synergistically enhance the flame retardancy and smoke suppression of epoxy resin (EP) by co-modifying Mg-Al layered double hydroxide (LDH) with sodium dodecyl sulfate (SDS) and sodium dodecylbenzene sulfonate (SDBS). This dual-surfactant approach is novel as it integrates two distinct functionalities—linear alkyl chain compatibility provided by SDS and aromatic sulfonate-induced charring contributed by SDBS—resulting in a synergistic improvement in LDH dispersion, interfacial bonding, and catalytic char formation, thereby achieving superior fire safety performance in EP composites. The modified SDS + SDBS-LDH was synthesized via a green ion-exchange route and uniformly dispersed in EP at a loading of 5 wt%. In cone calorimeter tests, total heat release and total smoke production decreased by 33.3% and 22.9%, respectively, while CO and CO 2 release rates dropped by 75.8% and 48.7% compared with pure EP. When applied as a coating, EP/5SDS + SDBS-LDH reduced the back-surface temperature of wood by 76.1%, demonstrating excellent thermal insulation and practical potential. This work provides a scalable and eco-friendly strategy for designing high-performance, flame-retardant epoxy composites through synergistic dual-surfactant modification of LDH.

The development of green and environmentally friendly flame retardant materials has attracted widespread attention in modern architecture. In this work, a kind of novel aerogel was prepared by the incorporation of Al(OH) 3 coated hollow glass microspheres (HGM) into konjac glucomannan (KGM) matrix and then cross-linking by CaCl 2 (abbreviated as KGM-HGM-Al(OH) 3 ). The prepared KGM-HGM-Al(OH) 3 aerogel exhibits a porous structure with a high porosity of 93.93%, endowing it with excellent thermal insulation performance. In addition, it exhibits excellent thermal stability, and the mass loss of KGM-HGM-Al(OH) 3 aerogels is 37.6% at 800°C. More importantly, the aerogel shows excellent flame retardancy, with the peak heat release rate (pHRR) and total heat release (THR) of 21.43 kW m −2 and 1.895 kJ m −2 , respectively. Furthermore, the limiting oxygen index (LOI) is 54.5%; this superior performance is primarily attributed to the synergistic effect of HGM-Al(OH) 3 . The hollow structure of the hollow glass microspheres effectively delays the internal heat transfer, Al(OH) 3 decomposes endothermically at high temperatures to form an Al 2 O 3 barrier layer, while releasing water vapor to dilute combustible gas, so that the KGM-HGM-Al(OH) 3 aerogel has excellent flame retardancy. The aerogel material has the advantages of low cost and a simple preparation method, and has extensive application value in the fields of building fire resistance and battery fire resistance.

Light diffusion film is a functional optical material designed to transform intense and non-uniform light from point or line sources into uniformly distributed, soft, and glare-free surface illumination through the scattering effect of embedded diffusion particles. In this study, raspberry-like composite particles were synthesized via electrostatic adsorption between PMMA microspheres and nano-sized SiO 2 . These particles were subsequently blended with a polysiloxane-modified acrylic resin, diluted, and coated onto a polyethylene terephthalate (PET) substrate to fabricate a light diffusion coating. The surface morphology of the composite particles and the resulting diffusion film was characterized using scanning electron microscopy (SEM), polarized optical microscopy, and confocal laser scanning microscopy. Optical performance, including transmittance and haze, was evaluated using a transmittance/haze meter and a UV-visible spectrophotometer. Compared to the pristine PET substrate, which exhibited a transmittance of 89.2%, the optimized diffusion film—achieved at a 6 wt% loading of diffusion particles relative to the acrylic resin—demonstrated superior light diffusion properties with a transmittance of 80.2% and a haze of 91.0%. Furthermore, the underlying light diffusion mechanism was systematically investigated.

The novel cross-linked copolymer (BPSU-C4A-SPS) was synthesized by the copolymerization of benzoxazine-functionalized polysulfone (BPSU), calix[4]arene (C4A), and sodium 4-hydroxybenzenesulfonate (SPS). The material exhibited high thermal stability with a glass transition temperature ( T g ) of 285°C and a 5% weight loss temperature ( T d5 ) of 347°C, and enhanced hydrophilicity with a water contact angle of 76.5°. Moreover, adsorption studies on MB demonstrated that BPSU-C4A-SPS possesses a higher adsorption capacity than the benzoxazine-functionalized polysulfone homopolymer (BPSU-a) and the benzoxazine-functionalized polysulfone-calix[4]arene copolymer (BPSU-C4A). Adsorption followed the Freundlich isotherm and pseudo-second-order kinetics best describes the adsorption process of BPSU-C4A-SPS to MB, indicating multilayer chemisorption driven by electrostatic interactions and π-π stacking. This work provides a scalable strategy for designing stable adsorbents with synergistic effects, suitable for industrial wastewater treatment.

Nanofiltration plays an increasingly important role in liquid separation scenarios. Membrane preparation processes are important factors affecting the separation effect of nanofiltration. Protein molecules are often added to the preparation process of nanofiltration membranes to improve their precise separation performance. Sericin is a protein material with excellent water solubility, and it doesn't pose any additional harm to the environment. In this study, a sericin-assisted interfacial polymerization process for nanofiltration membrane was proposed to improve the membrane forming process. The sericin in aqueous solution improved the surface properties and pore structure of the separation layer. After careful verification, we believed that the nanofiltration membrane prepared using 1% piperazine, 0.1% 1,3,5-Benzenetricarbonyl trichloride, and 0.02% sericin had the best performance. It showed a rejection rate of Na 2 SO 4 99%, MgSO 4 98%, MgCl 2 95%, NaCl 27%, LiCl 20%. At 2 bar operating pressure, the permeate flux could be increased from 15 to 25 L m −2 h −1 . The Mg 2+ /Li + separation factor could reach 20, and the SO 4 2− /Cl − separation factor could reach 60. The nanofiltration membrane had excellent salt separation performance. It had a great application prospect in seawater desalination pretreatment, lithium extraction from salt lakes, and water softening.

Perovskite-quantum dot (PQD) photoresists exhibit excellent optoelectronic properties and have become key modules for the construction of next-generation optoelectronic devices, including micro-LEDs, lasers, and optical anti-counterfeiting. However, traditional preparation of PQD photoresist requires a lot of solvent, harsh conditions, and a time-consuming process, which hinders the development of PQDs. Herein, we demonstrate in situ synthesis of CsPbX 3 (X = Br, Cl) PQDs photoresist based on polymerizable monomer tricyclic decane dimethanol diacrylate (TCDDA) for 3D printing. TCDDA not only acts as an eco-friendly solvent and efficient ligand to synthesize and stabilize the PQDs, but also serves as a functional monomer for photopolymerization to encapsulate the PQDs. The PQD photoresist is suitable for photolithography on different substrates, including metals, inorganic materials, polymers, and even paper. Furthermore, we performed 3D printing of arbitrary 3D objects with the smallest feature size of 17 μm by using the PQD photoresist. As a proof-of-concept, we depict the potential application of the PQDs photoresist for optical encryption through the construction of quick response (QR) codes and binary codes. This study provides a versatile method for the synthesis of PQD photoresist, and will pave the way for potential applications in flexible optoelectronic devices and anti-counterfeiting.
