NOVELTY - The preparation method of thiourea functionalized nano-graphene antibacterial material involves (1) reacting organic acid at 150-300 degrees C for 1-10 hours to obtain nano-graphene, (2) reacting the nano-graphene with thiourea organic ammonia antibacterial agent under the action of catalyst to obtain thiourea functionalized nano-graphene, and (3) polymerizing the thiourea functionalized nano-graphene and polymer material or directly subjecting to antibacterial test. USE - Preparation method of thiourea functionalized nano-graphene antibacterial material. ADVANTAGE - The method enables preparation of thiourea functionalized nano-graphene antibacterial material with strong antibacterial ability and excellent safety, and which is convenient to use.
