▎ 摘　　要

NOVELTY - Preparing hydrophilic reduced graphene oxide with macroporous structure comprises (1) using hummers method to prepare graphene oxide, and the graphene oxide aqueous solution is prepared by ultrasonic stripping, (2) adding dicyandiamide or melamine to graphene oxide aqueous solution, stirring, and allowing to stand for 10-24 hours, removing supernatant, filtering, and thermally annealing resulting filter cake to obtain a reduced graphene oxide coating whose core is dicyandiamide or melamine particles, and (3) adding a solvent to reduced graphene oxide coating, stirring, filtering with suction and washing with solvent, after drying to obtain macroporous structure of hydrophilic reduced graphene oxide. USE - The preparing hydrophilic reduced graphene oxide with macroporous structure is useful for preparation of paints or coatings (claimed). ADVANTAGE - The graphene oxide: is easy to disperse in water, has macroporous structure, good hydrophilicity and conductivity. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for hydrophilic reduced graphene oxide with macroporous structure.
