| 英文摘要 | Two simple and effective methods, "click" chemistry and supramolecular interactions, are demonstrated here to synthesize well-defined poly(L-lactide) (PLLA) functionalized graphene oxide (GO) sheets. We provide a simple method to introduce azide groups on GO sheets by the ring opening reaction of sodium azide with the epoxide groups of GO. The GO-N-3 sheets can easily undergo "click" reaction with alkyne-terminated PLLA by "grafting onto" method to produce GO/PLLA composites with high grafting ratio and exfoliated structure. Interestingly, GO-N-3 can be grafted with oxygen-containing polymers such as PLLA, polymethyl methacrylate (PMMA) or polyethylene oxide (PEO) via supramolecular interactions between the azide groups and these oxygen atoms on polymers, producing GO/polymer composites with low grafting ratio and intercalated structure. These "grafting onto" methods are useful to produce a variety of GO/polymer composites with different structure via "click" reaction or supramolecular interactions, which have potential applications in material science.
