Abstract :
New polymeric composite membranes polysulfone-polypyrrole has been prepared by a new technique consisting in phase inversion accompanied by chemical reaction. The membranes were synthesised from polysulfone/pyrrole-N, N´-dimethylformamide/ methanol system by phase inversion followed by remaining pyrrole in membrane pores polymerization in the presence of iron chloride. The obtained membrane was characterized by Fourrier transformed infrared spectroscopy (FT-IR), Thermogravimetric analysis (TGA), X-ray photoelectron spectroscopy (XPS) and electrochemical characteristics were determined by Electrochemical Impedance Spectroscopy (EIS).
