NOVELTY - Synthesizing polynaphthylamine-supported graphene involves adding naphthylamine monomer and graphite oxide to an acidic aqueous solution, ultrasonically dispersing to obtain a purple-brown sol (sol A), dissolving the oxidizing agent in an acidic aqueous solution and adding slowly dropwise to the sol A to obtain a mixed sol. The mixed sol is placed in a heat preservation apparatus and stirred at a constant temperature to obtain a black precipitate. The black precipitate is washed and dried to obtain an intermediate product polynaphthylamine-supported graphene oxide powder which is subjected to electron beam irradiation to obtain a final product of polynaphthylamine-supported graphene powder. USE - Method for synthesizing polynaphthylamine-supported graphene. ADVANTAGE - The method enables to prepare polynaphthylamine-supported graphene which has good sensitivity.
