In the present work, synthesis of PANI and PPy was carried out by chemical oxidative polymerization. The effect of synthesis parameters on the conductivity of the polymers was studied. The synthesized polymers, at optimized conditions of conductivity, were further characterized by XRD, SEM, FTIR, and TGA. Pure polysulphone membrane and its composite with the synthesized conductive membrane were carried out using immersion precipitation phase inversion. The synthesized membranes were characterized by FTIR, confocal microscopy, and TGA. The membranes were compared on the basis of various performance properties. It was observed that the pure water flux and water permeability increased in the order PSf < PSf/PANI < PSf/PPy. The composite membranes showed higher porosity, hydrophilicity, and better anti‐fouling characteristics compared to the pure PSf membrane.
