▎ 摘  要

The thermal stability of fluorinated graphene (FG) plays an important role in its application and research, and thus it is necessary to conduct in-depth research on the thermal stability of the C-F bond in FG. Herein, FG with different types and distributions of C-F/C(-F)(2) bonds were synthesized, and the correlation between the C-F/C(-F)(2) bonds and thermal stability of these FG samples was monitored via in situ heating infrared spectroscopy (in situ FTIR). The stability of the different types and distributions of C-F/C(-F)(2) bonds in FG and the temperatures at which these C-F/C(-F)(2) bonds were eliminated were determined. In terms of C-F bonds in FG, the most stable type is that in C(-F)(2) of perfluorinated FG, followed by the C-F bonds in perfluorinated FG. The thermal stability of isolated C-F bonds and C(-F)(2) bonds adjacent to the conjugated structure was the worst, which would be detached from FG at low temperature (
