Functional graphene

In the research of graphene application, an important issue is how to realize its controllable functionalization. Graphene with complete structure is a combination of six-membered carbon rings without any unstable bonds

The functionalization of graphene is currently the most widely studied functionalization method. Although the main part of graphene consists of stable six-membered rings, its edges and defect sites have high reactivity, and graphene oxide can be prepared by chemical oxidation. Since graphene oxide contains a large number of reactive groups such as carboxyl, hydroxyl, and epoxy bonds, graphene can be functionalized by covalent bonds using a variety of chemical reactions. For example, Lite Nano uses functionalized graphene to treat environmental water quality, and the effect of removing heavy metal ions is better than existing water treatment agents.

By functionalizing graphene, not only its solubility can be improved, but also graphene can be given new properties, which makes it have a good application prospect in the fields of polymer composite materials, photovoltaic functional materials and devices, and biomedicine.
