Abstract: Multilayer graphene as a potential anti-oxidation barrier to protect nickel foils from oxidation was studied in simulated primary water of pressurized water reactors (PWRs).The results show that after immersion for 1000 h,the structure of the multilayer graphene remains unchanged and no obvious oxide film formed on the graphene coated nickel foils,indicating multilayer graphene can effectively act as the anti-oxidation barrier to protect the substrate from oxidation and hence can improve the heat transfer efficiency of the substrate in simulated primary water of PWRs.
