▎ 摘　　要

A non-covalently modified graphene was fabricated under the presence of 1-allyl-methylimidazolium chloride (AmimCl) ionic liquid by reduction of oxidized graphene with hydrazine hydrate. The structure and the property of modified and unmodified graphene were characterized. by FTIR, XPS, UV-Vis, AFM, Raman spectroscopy and XRD. The prepared graphene can be dispersed homogeneously in dimethylformamide (DMF) and butyl acetate by ultrasonic treatment. The results reveal that the pi-pi and cation-pi interactions exist between AmimCl ionic liquid and graphene, and appromixmately 7.20wt% AmimCL is attached to surface of graphene. Meanwhile, AFM result shows that modified graphene is exfoliated in DMF with an average thickness of 0.962 nm. The maximum dispersibility concentration of modified graphene in DMF and butyl acetate is 1.69 mg.mL(-1) and 1.12 mg.mL(-1) respectively.
