▎ 摘　　要

NOVELTY - An asymmetric modified graphene or graphene oxide is prepared by preparing graphene or graphene oxide aqueous dispersion solution, adding water immiscible liquid organic phase and 10-18C alkyl chain quat. ammonium salt cationic surfactant, oscillating or stirring, transferring into organic phase/water interface, adding modified material, adsorbing, and separating. USE - Method for preparing asymmetric modified graphene or graphene oxide (claimed). ADVANTAGE - The graphene surface energy is easy to wrinkle and not easy to paved.
