Facile Corrosion Protection Coating from Graphene

Abstract—Corrosion is a serious global problem, affecting our daily lives and causing million dollar lost in industry annually. Chemical reaction occurs when metal surface comes in contact with oxygen in air, resulting metals being oxidized and corroded. Various methods have been employed by the industries to protect metal from corroding, such as applying coating with paints and varnishes. However, each method has its own limitations, such as modification of the protected metal, thickness of the coating, altering the dimensions and conductivities of the metal and enormous cost involves in the coating process. Therefore, the challenge in developing a protection barrier from corrosion is to develop an economical yet efficient method for the coating material. In this project, we developed a cheap and facile method of coating metal surface with graphene layer for corrosion protection. Starting from common graphite powder, graphene coating was deposited onto copper plate via electrophoretic deposition (EPD) method. The deoxygenation of carbon was confirmed by bathochromic shifting in UV spectroscopy. Graphene protection layer was further characterized electrochemically via potentiodynamic polarization testing in chloride solution. Potentiodynamic polarization curves show the decrease of both corrosion potential (Ecorr) and corrosion current (icorr), suggesting graphene protection layer decreases the copper dissolution process.
