Abstract :

Conducting polymers find wide application in fields like sensors, batteries, membranes, capacitors etc. Among all the conducting polymers, polyaniline (PANI) and polypyrrole (PPy) are widely investigated, owing to their easy synthesis process and applicability in many fields. These polymers can be synthesized using either chemical or electrochemical oxidative polymerization technique. In present work, synthesis of PANI and PPy was carried out by chemical oxidative polymerization. The effect of temperature and monomer: oxidant ratio on synthesis of PANI was investigated. Whereas, effect of type of oxidant and solvent on synthesis of PPy, was studied. Both the synthesized polymers, for which optimum value of conductivity was observed, were further characterized by XRD, SEM, FTIR, TGA and DSC. The synthesized PANI confirmed crystalline nature and fiber like morphology. The synthesized PPy was of amorphous in nature with spherical morphology. Synthesis of pure polysulfone membrane and its composite membranes with PANI and PPy was carried out using immersion precipitation phase inversion technique. The synthesized membranes were characterized by FTIR, confocal microscopy and TGA. The performance properties of synthesized membranes, such as pure water flux, permeability, hydrophilicity, pore size, porosity, flux recovery ratio, were investigated. It was observed that, addition of conducting polymers increases the hydrophilicity, pore size, anti fouling tendency of the membrane.
