In this study, a PMMA-b-PS anion-exchange membrane with high thermal and chemical stability is obtained by mixing polymethyl methacrylate (PMMA) and polystyrene (PS) using the film-casting method. PS is synthesized by radical polymerization and subsequently chloromethylated. Chloromethylated polystyrene is quaternized by adding trimethylamine (TMA) to the PS ring. The structure of the synthesized polystyrene was characterized by FTIR and 1H NMR spectroscopy. Thermal analysis of the polymers was carried out by TGA and DSC analysis, according to which the first thermal decomposition started at approximately 200 °C and the backbone dissociated at 450 °C indicating that the membranes maintained their thermal stability at high temperatures. The solution resistance, conductivity, and stability of the PMMA-b-PS membrane were measured by EIS in 1 M KOH, and a hydrogen volume of 30.8 mL was obtained after repeated electrolyzer measurements for an hour.
