Abstract

PANI (Polyaniline) is synthesized via chemical route based on chemical oxidative polymerization and thereafter in-situ doped with hydrochloric acid and different weight percentage of Lithium perchlorate. Thin films of Polyaniline and its different doped variant are deposited on plain soda glass and ITO conducting glass with chemical bath deposition technique. The obtained sample configurations are characterized by XRD for structural consistency, FTIR for chemical identification, DSC for thermal stability and electric measurements for capacitance and conductance are carried out with LCR and Four Probe arrangements respectively. XRD analysis reveals largely the polycrystalline nature of Polyaniline and its doped variant. FT-IR study of Polyaniline is found to be in good agreement with standard pronounced peaks in the region of 2000-3500 cm-1, a slight shifting in the doped Polyaniline is due to displaced hydrogen bonds. DSC reveals significant thermal stability of doped and undoped Polyaniline below 200 0C. Dielectric measurements in the frequency range 50 Hz - 2 MHz with variable temperature yields the variation of capacitance, that confirms the interfacial polarization in the PANI matrix. Lithium perchlorate doped PANI exhibits conductivity of 6.19 Sm-1 confirming the existence of bipolaron at higher level of oxidation.
