Abstract: The ability to protect refined metals from reactive environments is vital tomany industrial and academic applications. Current solutions, however,typically introduce several negative effects, including increased thickness andchanges in the metal physical properties. In this paper, we demonstrate for thefirst time the ability of graphene films grown by chemical vapor deposition toprotect the surface of the metallic growth substrates of Cu and Cu-Ni alloyfrom air oxidation. SEM, Raman spectroscopy, and XPS studies show that themetal surface is well protected from oxidation even after heating at 200\degree C in air for up to 4 hours. Our work further shows that grapheneprovides effective resistance against hydrogen peroxide. This protection methodoffers significant advantages and can be used on any metal that catalyzesgraphene growth.
