Electrical properties of polymer composties: conducting polymer-polyacene quinone radical polymer

Abstract Unique electrical properties are observed in conducting polymer such as poly(3-alkylthiophene) containing various types of polyacene quinone radical polymers (PAQR) such as PMA+Py. Electrical conductivity and its temperature dependence are strongly dependent on concentration of PAQR. Dependences of dielectric properties of the polymer composite on concentration of PAQR and temperature are also anomalous. The results are discussed in terms of electronic band schemes of of both polymers.
