Influence of matrix on conductivity properties of crystalline network of α-(BEDT-TTF)2I3 in polymer composites

The influence of the polymer matrix on the structure and electrical properties of conducting network containing α-ET2I3 polyiodide crystallites has been investigated. Polycarbonate and polystyrene were used as the matrices. The conducting properties were investigated by means of direct current and microwave conductivity (10.2 GHz) measurements in a broad temperature range and are discussed together with results obtained from AFM technique.
