Graphene as an anti-corrosion coating layer
WebJan 27, 2024 · Compared to the single layer graphene coating, double-layers graphene coating has a better anti-corrosion effect. This is in that the double-layers graphene coating can block the defects of the single-layer graphene in time, and better prevent the intrusion of Cl − into the copper matrix, so as to achieve a good anti-corrosion effect. WebThe study has led to the following conclusions: 1. Methods to produce low-cost industrially scalable graphene-based anti-corrosive coatings for copper in 3.5 wt% NaCl have been proposed. 2. Potentiodynamic polarization and EIS data indicate lower corrosion current densities for graphene-coated samples.
