The Preparation and Characterization of ZnO/Graphene Nanocomposites

Graphene-based composites now has been payed more and more attention to because it can make up many shortcomings of the pure single-layer graphene.In many papers ,there are one same phenomenon said that graphene can not be well dispersed in matrix since it’s high specific surface area and high surface energy.In this work,we reported the preparation of ZnO/graphene nanocomposites through the way of situ-reaction in the surface of graphite oxide.Then,the nanocomposites were characterized by X-ray diffraction (XRD), Fourier Transform-Infared spectroscopy (FTIR),transmission electron microscopy (TEM), and thermogravimetry (TG). The results indicated that the graphene oxide had been reduced by hydrazine hydrate and the ZnO crystal attached to the surface of graphene well.The ZnO/graphene nanocomposites can be expected to be dispersed in some kinds of rubber to improve their electric and thermal conductivities in the following experiments.
