Graphene-zinc oxide nano-composite materials with good performance were prepared by wet chemical methods. The results show that graphene/zinc oxide nanoparticles are synthesized successfully and analyzed by X-ray diffraction analyzer, scanning electron microscopy (SEM) and transmission electron microscopy (TEM). The size of ZnO nanoparticles is about 50 nm. G/ZnO/PMMA organic glass, ZnO/PMMA and G/PMMA organic glass were synthesized successfully by dispersing graphene/ZnO nanocomposite, graphene and zinc oxide in polymethyl methacrylate (PMMA) respectively by the casting method. Nonlinear optical scattering characteristics, nonlinear optical absorption properties and ultraviolet-visible absorption characteristics of G/ZnO/PMMA are all better than those of ZnO/PMMA and G/PMMA organic glass.
