Deposition and Characterization of Conducting Polymer (polyaniline) Thin Film in Electrical and Optical Application Using Chemical Deposition Technique

Abstract

Nano-structure polyaniline materials were deposited on glass substrate at room temperature,the material were doped using citric acid,formic acid,ammonia,hydrochloric acid and tetraoxosulphate(vi) acid.The optical and electrical properties of the polyaniline materials doped with dopants were investigated,the doped polyaniline material has high absorbance and transmittance in the wavelength range of 300-400nm.The energy band gap of the doped Nano-structure polyaniline varied from 2.41eV to 3.20eV,polyaniline material doped in HCl exhibiting the highest degree of conductivity making it most suitable doping agent in activating its electrical properties..Also from the result obtained we can deduce that dopants has a direct effects on the properties of polyaniline materials.
