NOVELTY - Preparing graphene/nanosilver composite material involves mixing 0.01 to 100 g/L aqueous solution silver nitrate and 0.01-100 g/L aqueous solution of graphene oxide, and mixing silver nitrate and graphene oxide in mass ratio 1:1 to 1:10, and adding bird's nest slowly. After ultrasonication, is placed in a reactor at 160-220 degrees C for 30-600 minutes, is repeatedly washed with ethanol, centrifuged, and dried to obtain graphene/nano-silver composite. USE - Method for preparing graphene/nanosilver composite material. ADVANTAGE - The method enables to prepare graphene/nanosilver composite material in simple, moderate reaction and environment-friendly manner.
