NOVELTY - Graphene oxide for anticorrosive paint, has an oxygen element/carbon element molar ratio, and is prepared by using sulphuric acid and potassium permanganate USE - Graphene oxide for anticorrosive paint. ADVANTAGE - The graphene oxide is simple to prepare and cost-effective. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for: 1. A method for preparing graphene oxide, which involves oxidizing graphite by using sulphuric acid and potassium permanganate with the concentration of 87-92wt.% 2. An anticorrosive paint, where the content of graphene oxide in the coating solid component is 0.01-0.50wt.%.
