This manuscript present a synthesis of Polyaniline/ Titanium oxide/Grapheme oxide (PANI/ TiO2/GO) nanocomposites using an in-situ chemical oxidation polymerization of aniline in presence of colloidal graphene oxide (GO) nanoparticles and Ammonium peroxide sulfate (APS) use as an oxidant at 0-5°C in air. This paper deals with the systematic study of variation of capacitance with respect to frequency of pure Polyaniline (PANI), Polyaniline/ Titanium oxide (PANI/TiO2) and Polyaniline/ Titanium oxide/Grapheme oxide (PANI/TiO2/GO) nanocomposites. Samples are structurally characterized through scanning electron microscopy (SEM) technique. The study shows that capacitance of pure PANI enhances slightly on dispersing TiO2 at 2 wt% and further doping of GO at 0.3wt% improves capacitance for this sample.
