摘要：

Conductive polypyrrole-poly(vinyl alcohol) composites have been chemically prepared by exposing poly(vinyl alcohol) (PVA) films containing FeCl3 to vapours of pyrrole. The obtained films have been characterized by photoelectron spectroscopy analysis (XPS), optical absorption, scanning electron microscopy and electron microprobe analysis. XPS measurements show that Fe3+ in PVA is reduced to Fe2+ during the polymerization reaction, confirmed also by optical measurements. A detailed analysis of the films with a scanning electron microscope equipped with an electron microprobe shows that PVA-PPy-FeCl3 compounds are homogeneous composites. It is also shown by XPS that covalently bonded chlorine is presumably present in the films and diffuses with time towards the surface of the sample. This chlorine release has been checked by electron microprobe analysis.
