Terpolymerpoly[aniline-co-(o-anisidine)-co-(o-toluidine)]was prepared by chemical method. The polymer solution deposited on interdigitated finger electrode by the use of spin coating technique. The thickness of the samples is measured by micro meter digital , Transform Infrared (FTIR) spectra, were used to characterize the molecular structures of copolymer.The electrical properties were investigated. The conductivity values of this polymer is (3.6x10-10, 1.5x10-7 S/cm) for both pure and doped polymers respectively, and increasing with increase temperature. The activation energy was determined from this curves were ( 0.34 ev, 0.24 eV) for copolymerpoly[aniline-co-(oanisidine)- co-(o-toluidine)]and poly[aniline-co-(o-anisidine)-co- (o-toluidine)-HCl] respectively .
