Abstract: Graphene composites have been prepared in this paper through the reaction between the amine group of 1-H,1-H-pentadecafluorooctylamine(FOA) and the carboxyl or alkoxy of graphene oxide(GO). The structures of the resulted composites were characterized by the means of FT-IR infrared spectrum, thermogravimetric analyzer, Raman microscope, high resolution transmission electron microscope, and atomic force microscope. The results indicated that the FOA molecule was linked to the edge of graphene. Meanwhile, the contact angle of the FOA-RGO composites was increased to 118° at room temperature compared with that of RGO(68°).

Key words: Graphene, pentadecafluorooctylamine, chemical modification, hydrophobicity
