To explore the usage of monolayer graphene as an anti-oxidation barrier in simulated primary water of pressurized water reactors(PWRs),we transferred the monolayer graphene synthesized by low pressure chemical vapor deposition(LPCVD) on Cu foil to Alloy 690 TT.After a 500 h immersion,strong oxidation resistance was obtained from the graphene coated Alloy 690 TT sample,indicating that the transferred monolayer graphene can act as an effective barrier to protect the substrate from oxidation in simulated primary water of PWRs.
