In order to combine the advantages of polysulfone (PSf) as a membrane material to that of polyaniline as a conductive polymer, one has attempted to obtain novel polysulfone-polyaniline composite membranes by a newly improved technique comparing to the existing ones. The strong point of this technique consists in a phase inversion by immersion precipitation accompanying by chemical reaction followed by the activation of polyaniline with sulfonated beta-cyclodextrine. The above synthesized membranes were structurally characterized using Scanning Electron Microscopy, FT-IR spectroscopy, thermal analysis. The ionic conductivity and electrochemical characteristics were also determined by Electrochemical Impedance Spectroscopy.
