Polyaniline-graphene oxide (PANI-GO) composites were obtained through in-situ chemical polymerization of aniline in a suspension of graphene oxide with different weight percentage. The synthesised nano composite materials were thin layer coated on glass and Al foil substrate. The PANI-GO nano composite thin films were studied by characterization of structural, functional groups analysis by XRD, FTIR spectroscopes. The optical absorption characterization of nano composite thin films by UV-Vis spectroscopy and supercapacitor performances of electrochemical analysis by using cyclic voltamatric (CV) technique. The result showed that structural study of XRD analysis showing as a synthesised nano composite as a amorphous nature and two small peaks present in spectral line, the optical absorption as a very small absorption in UV-Vis spectral regions of PANI-GO thin films, the electrochemical cyclic voltamatric analysis calculated specific capacitance value of PANI-GO nano composite thin film as 470.87 Fg-1.
