摘要
采用湿化学法制备了性能良好的石墨烯(G)/氧化锌(ZnO)纳米复合材料,利用X射线衍射分析仪、扫描电镜及透射电镜对其物理结构和形貌分析可知成功地合成了石墨烯/氧化锌的纳米颗粒,氧化锌纳米颗粒大小约为50 nm。分别将石墨烯/氧化锌纳米复合材料、石墨烯和氧化锌均匀地分散到聚甲基丙烯酸甲酯(PMMA)中通过浇铸法合成G/ZnO/PMMA有机玻璃、ZnO/PMMA和G/PMMA有机玻璃,对比可得,G/ZnO/PMMA的非线性光学散射特性、非线性光学吸收特性及紫外-可见光吸收特性较ZnO/PMMA和G/PMMA有机玻璃有了明显提高。
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.
