The bandgap of graphene remains unaltered with functionalization of its edges.

The bandgap of graphene remains unaltered with functionalization of its edges. Correct Answer True

The edge carbon atoms of graphene are more reactive than those of the basal plane. Their functionalization can improve both the solubility and assembly behavior of graphene. In contrast to graphene basal plane, functionalization of edge carbon atoms do not lead to any changes in bandgap, since the sp2 network remains undisturbed.
