▎ 摘　　要

NOVELTY - Aliphatic amine hydrophobically modified graphene oxide comprises a structure in which aliphatic amine segments are grafted onto the surface of graphene oxide. USE - The modified graphene oxide is useful for water-based coatings and preparing a marine water-based graphene anticorrosive coating (claimed). ADVANTAGE - The method adopts a simple one-step chemical method, characteristics of hydrophobic aliphatic chains and a large area of action, and reactivity of the amino group and the carboxyl group on the surface of the graphene oxide, and improves hydrophobic properties of graphene oxide while ensuring the dispersibility of graphene in an aqueous system. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing the modified graphene oxide, involving uniformly dispersing graphene oxide in an organic high-boiling solvent, removing hydroxyl group on the surface of the graphene oxide with a dehydrating agent, fully reacting the treated graphene oxide solution with aliphatic amine, and finally filtering, washing and drying to obtain the product.
