Preparation and properties of polypyrrole/bentonite/vanadium (V) oxide ternary composites

The preparation and characterization of new ternary composites formed by the redox/intercalative reaction of pyrrole with the lamellar bentonite/V2O5 composite are reported. The generation of a conducting polymer combined with a mixed semiconductor oxide-clay material provided an interesting material where the conductivity depends upon the polypyrrole content, and on the particular way it influences the Li+ ions migration in the films.
