NOVELTY - Modified graphene oil-in-water Pickering emulsion comprises 0.1-5 pts. wt. graphene-based pickering emulsifier, 8-20 pts. wt. organic phase, and 5-15 pts. wt. water. USE - The Pickering emulsion is useful in the field of colloid chemistry. ADVANTAGE - The Pickering emulsion has simple components, strong temperature resistance, strong stability and long service life. The method provides stable Pickering emulsion without co-emulsifier, which reduces the preparation process and cost. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method for preparing modified graphene oil-in-water Pickering emulsion comprising (1) adding organic phase to water, and stirring to obtain an oil-water mixture, and (2) adding graphene-based Pickering emulsifier in oil-water mixture, and stirring to obtain modified graphene oil-in-water Pickering emulsion.
