It has been attempted to improve the anti-static property of Nylon 6 by means of Vapor-phase polymerization of thiophene in Nylon 6/PVA blend films impregnated with aluminium chloride as an oxident. After Polymerization of thiophene for two hours in Nylon 6/PVA blend films the conductivity increased from $10^{-12}-10^{-13}S/cm;to;10^{-5}-10^{-7}$S/cm, and the conductivity of composite films increased with increasing the concentration of aluminium chloride, the content of PVA annd polymerization time of thiophene. Polythiophene introduced in Nylon 6/PVA blend films has been confirmed by FT-IR spectra and scanning electron micrographs.
