Effect of quasi-stationary electric field on charge transfer in poly(phenylene oxide) based composites

Abstract

The article explores the processes of charge transfer in the samples of polymeric composites based on poly(phenylene oxide) with fullerene and endometalfullerene in the electric field of low frequencies (f = 10−1Hz). The article identifies transfer processes connected with intramolecular and intermolecular conductivity. It is found that conductive channels are formed in a polymeric matrix at high concentrations of fullerene, thus, the type of conductivity changes from semiconductor to metallic. The embedding of iron into the fullerene frame molecule leads to the appearance of metallic conductivity of the composite in some temperature range.
