Abstract Due to their excellent alkali resistance and chemical stability, polyphenylene sulfide (PPS) fabric membranes are widely used in alkaline water electrolysis (AWE) for hydrogen production. However, traditional PPS suffer from poor hydrophilicity, low airtightness, high area resistance, resulting energy consumption reduced safety industrial applications. This study addresses the aforementioned issues by coupling 3‐(2,3‐epoxy propoxy) propyl trimethoxy silane (KH560) via self‐condensation membrane blending it with self‐synthesized yttrium‐stabilized zirconia nanoparticles (YSZNPs). The YSZNPs loaded onto modified fiber surface through dip‐coating hot‐pressing processes, forming a micro‐mechanical interlocking structure that enhances overall performance of practical production findings indicate developed composite demonstrate outstanding minimal (0.21 Ω cm 2 ), elevated bubble point pressure (2.93224 bar). Significantly, tests on gas purity produced oxygen attain purities 99.90% 99.75%, respectively, when evaluated at current density 1.5 A −2 . Moreover, after 500 h testing simulated environment, decline is observed, highlighting competitive edge this AWE market.

To address swelling, reduced mechanical strength, and high methanol permeability in sulfonated polyimide (SPI) proton exchange membranes, a composite membrane was developed by incorporating phenolic amine-modified porous expanded polytetrafluoroethylene (ePTFE) as reinforcing skeleton within the SPI matrix. The resulting (pore size: 0.1 μm) demonstrates conductivity of 0.42 S/cm at 80 °C, low swelling rates (4% surface, 10% thickness), tensile strength (33 MPa), (0.11 × 10–6 cm2/s). ePTFE enhances limits water absorption, ensures continuous transport. Additionally, hydrogen bonding between phenolamine groups on sulfonic acid further improves membrane's performance. This study presents straightforward strategy for developing high-performance membranes.
