Does graphene cause or prevent the corrosion of copper? New study finally settles the debate

Graphene has attracted the interest of researchers in recent years because, despite its apparent anti-corrosive properties, its proximity was seen to increase the corrosion of copper. A research team from Chung-Ang University used Raman spectroscopy to analyze graphene's properties over a long period and found that the corroded surface of copper forms a hybrid layer with graphene, which prevents further corrosion. These findings could have potential applications in extending the life of copper--a common component of various electronic devices.
