Abstract The pursuit of safer energy storage systems is driving the development of advanced electrolytes for lithium-ion batteries. Traditional liquid electrolytes pose flammability risks, while solid-state alternatives often suffer from low ionic conductivity. Gel polymer electrolytes (GPEs) emerge as a promising compromise, combining the safety of solids with the ionic conductivity of liquids. Cellulose, an abundant and eco-friendly polymer, presents an ideal base material for sustainable GPEs due to its biocompatibility and mechanical strength. This study systematically investigates how drying methods affect cellulose-based GPEs. Cellulose hydrogels were synthesized through dissolution-crosslinking and processed using vacuum drying (VD),… More >

Abstract The fabrication of highly flame-retardant polyamide 6 (PA6) composites is of great significance for expanding their practical applications. Herein, a new flame-retardant system (ADP/FA) was developed by combining aluminum diethylphosphinate (ADP) with excellent flame retardancy and fly ash (FA), an economical and environmentally friendly industrial waste. Due to the synergistic flame-retardant effect of ADP/FA in the condensed phase and gas phase, the PA6 composite containing only 11 wt% of ADP/FA (mass ratio 93:7) obtained vertical burning (UL-94) tests V-0 rating with a limiting oxygen index (LOI) of 30.9%. To obtain the same flame-retardant level of… More >

Abstract Anion exchange membrane (AEM) fuel cells require membranes with a balance of high conductivity and durability. In this work, a novel bi-crown-ether modified piperidine structure was designed and synthesized, which was then introduced into the side chain of poly(arylene piperidinium), making a unique bi-crown-ether modified bi-piperidinium side chain grafted polymer for AEM fabrication. The double crown ether units enhanced cation–water interactions and promoted microphase separation, thereby forming efficient hydroxide ion transport channels. The resulting membrane exhibited high water uptake, well-defined ion clusters, and a hydroxide conductivity of 123 mS cm−1 at 80°C with an ion exchange More >

Abstract Addressing the persistent challenge of shale hydration and swelling in water-based drilling fluids (WBDFs), this study developed a smart thermo-responsive shale inhibitor, Hyperbranched Polyethyleneimine-Propylene Oxide-N-isopropylacrylamide (HPN). It was synthesized by grafting hyperbranched polyethyleneimine (HPEI) with propylene oxide (PO) and N-isopropylacrylamide (NIPAM), creating a synergistic hydration barrier through hydrophobic association and temperature-triggered pore plugging. Structural characterization by Fourier-Transform Infrared (FTIR) spectroscopy and gel permeation chromatography (GPC) confirmed the successful formation of the HPN terpolymer, revealing a unique “cationic–nonionic” amphiphilic architecture with temperature-responsive properties. Performance evaluation demonstrated that HPN significantly outperforms conventional inhibitors, including potassium chloride (KCl),… More >

Abstract Carbon fiber-reinforced composites (CFRCs) have a wide range of applications in the aerospace, automotive, and energy sectors. A higher specific strength-to-weight ratio is desired in high-performance applications. The failure mechanism of CFRCs involves multiscale phenomena, such as failure that can occur at the matrix, fibers, interface, layers, lamina, and laminates. When an impactor hits the CFRCs, the design involves analyzing each of these stages to prevent failure and optimize the properties of CFRCs under various loading conditions. A numerical model was employed to predict the fracture toughness of CFRCs with varying weight fractions and orientations.… More >

Abstract Polymethyl methacrylate (PMMA) is widely used in diverse applications such as protective components (e.g., automotive lamp covers and structural casings), optical devices, and biomedical products, owing to its lightweight nature and impact resistance. However, its surface hardness and wear resistance remain insufficient under prolonged exposure to abrasive environments. In this study, a multi-filler strategy with nano-silica (SiO2), brominated lignin (Br-Lignin), and cellulose nanocrystals (CNCs) was employed to enhance PMMA tribological properties. SiO2 provided localized reinforcement, Br-Lignin established stable network structures, and CNCs improved compactness, enabling strong synergistic effects. As a result, the composites achieved up to More >

Abstract To study the behavior of structural dynamics, ionic conductivity and ion transport properties, the gel polymer electrolytes (GPEs) was developed using polyvinyl alcohol in combination with potassium iodide, dimethyl sulfoxide, ethylene carbonate, propylene carbonate and tetra-N-propylammonium iodide (C12H28IN), The GPEs were synthesized via a solution mixing technique, systematically varying the tetra-N-propylammonium iodide concentration to optimize ionic transport properties. The gel polymer electrolytes (GPEs) preparation was initially dissolving the potassium iodide and tetra-N-propylammonium iodide in a measured combination of ethylene carbonate, propylene carbonate, and dimethyl sulfoxide within a glass container. Subsequently, polyvinyl alcohol (PVA) was introduced into… More >

Abstract With the global diabetes epidemic, diabetic foot ulcers (DFUs) have become a major health burden, affecting approximately 18 million people worldwide each year, and account for about 80% of diabetes-related amputations. Five-year mortality among DFU patients approaches 30%, which is comparable to that of many malignancies. Yet despite standard wound care, only about 30%–40% of chronic DFUs achieve complete healing within 12 weeks. This persistent failure shows that conventional dressings remain passive supports. They do not counteract underlying pathologies such as ischemia, prolonged inflammation, and infection. Recent advances in polymeric nanofiber scaffolds, particularly electrospun matrices,… More >

Abstract MXene (Ti3C2Tx) is known for its excellent hydrophilicity, electrical conductivity, and dispersibility. It is a promising candidate for the fabrication of moisture-responsive actuators due to the strong interaction between MXene sheets and water molecules. Inspired by natural organisms, a variety of moisture-actuated soft robots have been successfully developed through the systematic integration of MXene-based actuators. This minireview summarizes recent advances in the preparation and applications of MXene-based moisture-responsive actuators. The hydrophilic properties of MXene, along with design principles, working mechanisms, current progress, and applications of MXene-based actuators, are discussed. The future prospects and developmental directions of More >
