▎ 摘  要

Graphene has got considerable attention in both experimental and theoretical fields for its extraordinary properties. Covalent functionalization is an efficient strategy to render graphene additional properties and overcome its shortcomings such as zero band gap and nondispersibility in solvents. This study reports the synthesis and characterizations of a new kind of functionalized graphene, graphene-TCNEO, obtained by 1,3-dipolar cycloaddition. The graphene-TCNEO was systematically characterized by FTIR, Raman, XPS, SEM, TEM, and EDS mapping, and the covalent linkage between graphene and tetracyanoethylene oxide was firmly verified. Considering the great diversity of nitrile chemistry, the obtained graphene-TCNEO could be further transformed into other graphene-based derivatives with interesting properties.
