▎ 摘　　要

A series of hybrid materials (a-GO@COF-Fs) were obtained by in situ growth of a two-dimensional covalent organic framework (COF-F) with strong electronegativity on the surface of aniline-functionalized graphene oxide (a-GO). It was found that the specific capacitance of a-GO@COF-F-5 is 295 F g(-1), which is a four-fold increase over pristine COF-F (71 F g(-1)).
