摘要：

Polypyrrole-thermoplastic composite films were obtained by casting. Homogeneous films were prepared with dispersant poly(vinyl methyl other) or poly(vinyl ethyl ether) by two methods. Electric conductivity, morphology, mechanical properties, and sensitivity to H2O2 in water were studied. Composites of polypyrrole with poly(vinyl chloride) carboxylated and poly(vinyl methyl ether) presented improved mechanical and electrical properties compared with other composites studied. These films were sensitive to H2O2 in water, showing a significant change in electric resistance. This change is discussed in relation to the H2O2 concentration and the exposure time.
