▎ 摘　　要

NOVELTY - The method involves mixing silver ammonia solution having predetermined mass fraction with a graphene oxide mixed solution. The solution is subjected to predetermined temperature. The polytetrafluoroethylene liner is placed into a hydro-thermal reaction kettle for 24 hours. After natural cooling, the ethyl alcohol and deionized water are repeatedly subjected to centrifuging and drying process to obtain graphene nano-silver composite material. USE - Preparation method for graphene nano-silver composite material. ADVANTAGE - Obtains a nano-silver graphite composite material using a simple technology that is environment-friendly. DESCRIPTION OF DRAWING(S) - The drawing shows a transmission electron microscopy image of the graphene nano-silver composite material.
