The Electronic transitions of polyaniline doped with p- toluene Sulfonic acid

Abstract

Polyaniline doped with p-toluene Sulphonic acid PAni-PTSAwas synthesized by using a new oxidative chemical polymerization method. The polymer solution deposited on, glass and Aluminum substrate by spin coating technique.Fourier Transform Infrared (FTIR) spectra, and ultraviolet visibility (uv- vis. absorption) spectra, were used to characterize the molecular structures of PAni-PTSA and electronic translation of polymer . The optical analyses indicated that the transition was direct transition with energy gape about 2.5eV. The electrical properties were measured by two probe method. The conductivity values of this polymer is about(8*10-4 S/cm ).
