NOVELTY - Preparation of white graphene dispersion, involves mixing hexagonal boron nitride powder, surfactant and solvent, grinding, placing obtained mixture in ball mill, ball milling at constant speed for a period of time, washing obtained powder with alcohol and drying. The mass ratio of hexagonal boron nitride powder to surfactant is 1:1-500:1. The mass ratio of hexagonal boron nitride powder to solvent is 2:1-1:10. The mass ratio of hexagonal boron nitride powder is 5-40%. The ball milling is carried out for 120-480 hours. USE - Preparation of white graphene dispersion (claimed). ADVANTAGE - The method enables preparation of white graphene dispersion with high purity, large specific area and dispersibility.
