摘要： 通过化学法改性石墨烯，用全氟辛胺(FOA)的胺基与氧化石墨烯（GO）的羧基或烷氧基反应制备了含氟石墨烯复合材料（FOA-RGO），用傅里叶红外光谱、热失重分析、拉曼光谱、高分辨透射电子显微镜（HRTEM）以及原子力显微镜（AFM）对复合材料的结构与形貌进行了表征。 结果表明，FOA已经成功地修饰到石墨烯的边缘。与未修饰的石墨烯相比，水滴在FOA-RGO表面上的接触角从68°提高至118°,显示出良好的疏水性能。

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
