Electrical conductivity of a copolymer of N-vinylcarbazole and divinylbenzene
The current-voltage characteristics and the temperature dependence of electrical conductivity of polyvinylcarbazole and of a copolymer of vinylcarbazole and divinylbenzene have been determined. No essential differences in the character of electrical conductivity of polyvinylcarbazole and that of copolymer have been observed. The strong polarization effects observed in both cases are caused by the reorientation of polar carbazole groups in electrical field. The high-field conductivity of both polymers could be explained by using the Poole-Frenkel model of volume effects.
