Reduced graphene oxide (rGO) was synthesized from graphite powder employing a modified Hummers method. The (PANI)1-x(rGO)x composites (x = 0, 0.02, 0.04, 0.06, 0.08) were prepared by an in-situ chemical oxidation polymerization of aniline using ammonium peroxydisulfate (APS) as an oxidant in presence of colloidal rGO to improve thermal stability of PANI. The samples were characterized by X-ray diffractometry using CuK (λ = 1.5407 Å) in order to study the phase and orientation of composites. Raman spectroscopy analysis of PANI/rGO nanocomposites was performed using confocal Raman microscopy. To measure the thermal stability, thermogravimetric analysis was done for PANI and PANI/rGO nanocomposites.
