Saad Lamouri, Soumia Bendahgane and Atika Oudia

Polyaniline free-standing films behavior has been investigated by electrical measurements, spectral, thermal and morphological analyzes. Two categories of thin films were elaborated. The first one represents films containing intrinsic conducting polymer, Polyaniline (PANI), doped by dipping method in sulfanilic acid solutions for various period of time. The second category contains conducting polymer composite; Polyaniline-Polyvinylchloride (PANI/ PVC), prepared by co-dissolution method using sulfanilic acid as a doping agent and N-methylpyrrolidone (NMP) as solvent and deposited on glass substrate using the spin coating technique. The effect of doping time, PANI fraction and film thickness on the conductivity has been studied principally by electrical measurements.
