Abstract

The microstructure and electrical property relationships in conjugated polymer composites( polyaniline (PAn) or polypyrrole(PPy)/thiokol rubber (TR)) have been characterized by 4-probe method , scanning electron microscope (SEM), x-ray energy dispersive spectrometer (EDS) and attenuated total reflection(ATR). The electrical conductivities of the two surfaces of the film, with film thicknesses from 0.01mm to 0.30mm, prepared by electropolymerization , were measured . The differences were related to the thickness of the film. As for a similar PPy/TR film, when trichloroacetic acid was regarded as the supporting electrolyte the film thickness was 0.05mm and the electrical conductivity of the surface on the solution side was reduced by about 21.3%. The studies of SEM, x-ray EDS , ATR for the chemical composition and microstructure of the two surfaces of the composite films showed that a reaction layer was present in the films. Moreover , the conductivity changes between two sides of a fold mark in the conducting composite film is discussed.
