This book systematically summarizes the great potential applications of graphene in the field of metal corrosion protection graphene anticorrosion films graphene/organic anticorrosion coatings graphene/Inorganic anticorrosion coatings and graphene/polymer anticorrosion coatings. In spite to corrosion protection graphene coatings have been applied as flame-retardant coatings wear/scratch-resistant coatings antifouling coatings pollutant-adsorption coatings and antiseptic coatings.
