▎ 摘 要
NOVELTY - Amidated modified graphene oxide, obtained by modifying graphene oxide by 2-aminobenzimidazole is claimed. USE - The modified graphene oxide is useful in epoxy anti-corrosive coating, preferably epoxy coating of composite filler (claimed). ADVANTAGE - The method does not require excessive equipment, and is simple and convenient to operate. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing amidated modified graphene oxide comprising dissolving graphene oxide in an organic solvent, dispersing it uniformly, adding 2-aminobenzimidazole, heating and reacting, after completing reaction, cooling, filtering and drying to obtain amidated modified graphene oxide.
