NOVELTY - The preparation of graphene micro sheet involves (1) dissolving surfactant as graphene modifier in pure water, (2) adding graphite and surfactant solution to colloid mill, operating mill, grinding, stripping to modify graphene surface and enhance hydrophilicity, (3) stirring suspension, saturating using ultrasonic probe with frequency 20-80 kHz, adjusting dispersion temperature to 0-20 degrees C, dispersing for 1-10 hours to obtain modified graphene dispersion, (4) dissolving shell material in water, adding shell material aqueous solution to graphene dispersion, and spray drying. USE - Preparation method of graphene micro sheet for aqueous anticorrosive coating. ADVANTAGE - The method enables preparation of graphene micro sheet with improved solubility and compatibility.
