▎ 摘 要
NOVELTY - Preparing graphene-copper composite powder comprises performing the first electrolysis by anode stripping; performing a second electrolysis by electrolytic deposition; where the first electrolysis adopts a first anode and a first electrolyte, the first anode is graphite, and the first electrolyte comprises sulfate and a surfactant. The second electrolysis adopts a second electrolyte, and the second electrolyte comprises graphene and copper salt. USE - The method is useful for preparing graphene-copper composite powder. ADVANTAGE - The powder has low oxidation degree, high single layer rate, less defect, complete structure, high specific surface area and high reduction degree. The method is simple and economical; has short preparation time, mild reaction condition. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a graphene-copper composite powder prepared by the above method.
