▎ 摘　　要

A noncovalent functionalization of the edges of reduced graphene oxide (RGO) with -cyclodextrin-graft-hyperbranched polyglycerol (-CD-g-HPG) was successfully performed via a host-guest interaction. The results showed that -CD-g-HPG disperses the graphene sheets better than pure -CD or HPG. The resulted supramolecular structure is stable in neutral water medium more than one week. However, in acidic medium the host-guest interaction is collapsed and graphene nanosheets precipitate. [GRAPHICS]
