The luminescence behavior of carbon nanotubes was achieved by grafting polybenzimidazole on its surfaces. The polybenzimidazole-grafted carbon nanotubes composite was analyzed for its optical and electrochemical properties. From the studies, it was observed that the polybenzimidazole emits blue light at 448nm, whereas the polybenzimidazole-grafted carbon nanotube shows a red shift with corresponding emission at 434nm. Additionally, the lifetime of exciting electrons has been calculated from the lifetime measurement studies. The polybenzimidazole-grafted carbon nanotube composite also possess 130F/g of specific capacitance. Micrograph analysis confirms the grafting of polybenzimidazole on the walls of the carbon nanotube.
