▎ 摘　　要

NOVELTY - Graphene oxide is diffused in water as carrier, and chloroauric acid is directly reduced on the surface of water by in-situ method to form uniformly arranged nano gold particles to obtain nano gold/graphene oxide composite material. USE - Preparation of nano gold/graphene oxide composite material (claimed) used as conductive material. ADVANTAGE - The method provides nano gold/graphene oxide composite material with uniform particle size distribution, improved conductivity and biocompatibility, by stable and simple process without adding protection agent.
