Polyaniline and its derivatives is one kind of important conductive polymer. In this paper, the active mechanism of substitution and doping on conductivity of polyanilines was studied by means of EHMO-CO method. The result showed that doping and substitution had different active mechanism on conductivity of polyanilines, doping lowered markedly the exciting energy of carrier, while substitution altered chiefly the band width.

Key words: Polyaniline and its derivative, Conductivity, EHMO-CO, Band width, Band gap
