Synthesis of polyaniline-graphite nanocomposites in aqueous media by in situ polymerization

Polyaniline (PANI) is a promising conducting polymer of high environmental stability possessing a wide range of controllable variation of optical, electrochemical and electricalproperties. PANI has been extensively studied for its application in sensors, batteries, light emitting and electrochromic devices, solar cells, etc1. Graphite nanoparticles have been incorporated into PANI matrices to improve its physiochemical properties andelectrical conductivity. In situ polymerization of Aniline inaqueous media has been used to ensure that PANI is intercalated into the interlayer space of graphite.2
