Abstract

Abstract: In this paper, series of models of the proton-doped polyaniline were calculated by using EHMO-CO method. The theoretically calculated energy band structure is in very good agreement with the experimental results on spectrum and is more satisfactory for explaining the conductive mechanism of the doped polyaniline. The theoretical study shows that the charged carriers are polarons in the doped polyaniline.
