Multi-layered type hybrid glass/polypyrrole composite

Multilayer organic xerogel—polypyrrole composites have been prepared by alternate successive treatments of a glass substrate with a siloxane functionalized pyrrole, pyrrole, oxidant, and a sol precursor of the xerogel. An increase of the conductivity is seen upon the first depositions, but increasing the deposit numbers over three fourfold layers does not lead to a further improvement of the conductivity. The loss of conductivity upon aging in air of the composites is weaker than in the case of ordinary unprotected polypyrrole.
