Characterization of EB-PANI, ES-PANI and Copper Doped PANI

Abstract

       Three types of polyaniline varieties EB-PANI, ES-PANI and copper doped PANI have been characterized. The p ®p* transitions are clearly exhibited in solution samples of PANI. However, the absorption spectra is thin films exhibit peaks at different values, explainable as per Stafstrom’s picture. The FTIR in all PANI varieties exhibit the characteristics of PANI chain. The copper linked vibrations are also seen for copper doped PANI. The X-ray spectrum are also all alike for different PANI varieties with an additional peak at a low 2q value for copper based PANI. The changes in morphology of films of PANI varieties are seen as per SEM photographs.
