Several recent reports describe using clay or other inorganic fillers to form CP composites. Polyani-line-polypyrrole composite coatings containing clay or yttria stabilized zirconia were electrodeposited onto AA 2024-T3 [158], with improved corrosion resistance of the substrate. Similarly, particulate-filled polyaniline and polypyrrole films on AA 2024-T3 were prepared electrochemically using a variety of fillers, including clay, carbon black, short carbon fiber, zirconia, and silica [159]. Again, enhanced corrosion performance for these composites was observed. 

Excluding the cases where the polymers are deposited onto ITO electrodes, there are few examples of composites of conductive polymers and glasses. The incorporation of polypyrrole into a Si02 matrix was achieved by incorporating pyrrole into Cu " containing silica gels, in bulk and thin-film form [165]. These...
