Properties of polymer conducting thin layers on the surface of microporous polyethylene films

Abstract

Thin layers of conducting polymers were formed on the microporous polyethylene film containing through flow channels. The films are characterized by the relief-like strongly developed surface. The layers were obtained by polymerization in gas phase (polypyrrole) or in solution (polyaniline). Conducting layers were located on the film surface and on the walls of channels. Conductivities of layers along the film surface (sheet) and between the film surfaces (volume), and also electrolytical conductivity of samples have been measured. Thermodeformational behavior of the samples under study and porous polyethylene support has been investigated. The effect of conducting polymer layer on structure transformations upon heating has been studied by WAXS, thermogravimetry, DTA and DSC.
