| Summary: | Since its experimental isolation in 2004, graphene has shown some outstanding properties. We propose that graphene can be used as an oxidation barrier coating and its oxidation resistance weakens at the graphene grain boundaries. Copper is a superior conductor but is easily oxidized in air at room temperature or higher. Using graphene as a coating material may reduce the cost of protecting against oxidation because copper is commonly coated with gold. The goal of the project is to investigate the breakdown of graphene as an oxidation barrier. Specifically, we studied the failure modes of this oxidation barrier coating which oxidations begin at the grain boundaries of the graphene coating. By determining its breakdown locations, additional sealant can be applied to those locations to enhance its oxidation resistance. |
