Abstract
In this work, hydrophilic and organophilic chemically modified graphene oxide (CMGO) sheets were prepared through a two-step diimide-activated amidation. The hydrophilic and organophilic products were characterized by atomic force microscopy, transmission electron microscopy and ultraviolet-visible spectroscopy. The resulted dispersions are homogeneous and exhibit long-term stability, which will facilitate the combination of CMGO sheets with polymers to yield homogeneous composites.
