NOVELTY - Preparation of surfactant comprises reacting subjecting styrene monomer to free-radical copolymerization with methacrylate and polyether macromer initiator, precipitating, and drying. The methacrylate is methyl methacrylate. The polyether macromer initiator is polyether polyol, polypropylene glycol 2000 or polypropylene glycol 3000. The surfactant has amphiphilic molecules having comb structure. USE - Method for preparation of surfactant used for controlling compatibility of controllable graphene (claimed). ADVANTAGE - The method is simple and environment-friendly, changes hydrophilic-lipophilic balance value of surfactant and adjusting its compatibility with graphene, and prepares a liquid phase to improve graphene mechanical peeling efficiency and accelerates industrialization process.
