NOVELTY - Graphite alkenyl composite material preparation involves dissolving chitosan in 3% acetic acid solution, and then performing ultrasonic treatment for 1-12 hours. The obtained material is mixed with 2-10 g/L sodium periodate for 10-60 minutes at 40-80 degrees C, and then the obtained material is centrifuged. The obtained material is washed with deionized water, and then dried them. The obtained material is mixed with certain amount of silver ammonia solution and graphene oxide mixed solution at 40-100 degrees C for 1-12 hours, and then heated them at 160-220 degrees C for 48 hours. USE - Method for preparing graphene alkenyl composite material (claimed). ADVANTAGE - The method enables to prepare graphene alkenyl composite material in simple and eco-friendly manner. DETAILED DESCRIPTION - Graphite alkenyl composite material preparation involves dissolving chitosan in 3% acetic acid solution, and then performing ultrasonic treatment for 1-12 hours. The obtained material is mixed with 2-10 g/L sodium periodate for 10-60 minutes at 40-80 degrees C, and then the obtained material is centrifuged. The obtained material is washed with deionized water, and then dried them. The obtained material is mixed with certain amount of silver ammonia solution and graphene oxide mixed solution at 40-100 degrees C for 1-12 hours, and then heated them at 160-220 degrees C for 48 hours in a hydro-thermal reaction vessel. The obtained material is mixed with polytetrafluoroethylene, and then cooled the obtained material naturally. The obtained material is washed with ethyl alcohol and deionized water, and then centrifuged them. The obtained material is dried to obtain the finished product.
