Abstract
In one aspect, a coating for protecting a component exposed to a corrosive environment includes an epoxy phenolic resin and graphene nanoplatelets. In another aspect, a method of protecting a an article exposed to a corrosive environment includes applying a corrosion-resistant epoxy phenolic coating to a surface of the article exposed to a corrosive environment and curing the corrosion-resistant epoxy phenolic coating. The coating comprises 0.1 to 2.0 weight percent graphene nanoplatelets containing 5 to 15 atomic percent oxygen.
