2020-10-24 · These findings show that graphene, in fact, protects copper from deep, penetrating oxidation, unlike what previous studies had concluded. Prof Son explained, "We observed that over a longer time scale (more than 1 year), the graphene-Cu 2 O hybrid structure became a protective layer against oxidation. The area beyond the graphene was heavily oxidized with CuO, with a depth of 270 …
