Method for preparing graphene load nano silver-nickel alloy composite powder materials

The invention relates to a method for preparing graphene load nano silver-nickel alloy composite powder materials. The method aims to solve the problems that graphene load nano silver-nickel alloy composite materials prepared in the prior art are nonuniform in scattering and poor in chemical stability. The method comprises the first step of intercalation and expansion, the second step of stripping and the third step of the preparation of the graphene load nano silver-nickel alloy composite powder materials. Oxidized graphene is prepared through an oxidation-reduction method, then the oxidized graphene, silver ions and nickel ions are mixed and restored through reducing agents to obtain the graphene nano silver-nickel alloy composite materials, the method is simple and fast, any surface dressing agent does not need to be added, and alloy particles on the surface of the graphene are uniform in distribution and stable in chemical performance. The method is used for preparing the graphene load nano silver-nickel alloy composite powder materials.
