NOVELTY - A preparation method of amphiphilic graphene comprises: dissolving 0.01-10 mg graphene oxide per 1 ml water-alcohol solution, ultrasonic dispersing; adding oil/oleic acid in the solution at 100:1-1:100 graphene oxide and oil/oleic acid mass ratio, stirring uniformly at 90-300 degrees C for 1-50 hours; washing repeatedly with chloroform organic solvent to obtain a lipophilic graphene; adding polyethylene glycol at 100:1-1:100 lipophilic graphene and polyethylene glycol mass ratio, stirring uniformly at 90-300 degrees C for 1-50 hours; and washing product with water-alcohol solution. USE - A preparation method of amphiphilic graphene. ADVANTAGE - The preparation method is simple, low cost, and consumes low energy.
