摘　　要：采用了改进的Hummers法制备氧化石墨烯(GO),并使用绿色环保的还原剂葡萄糖还原银氨溶液中的银氨离子,在没有分散剂的情况下,制备了氧化石墨烯/银纳米复合颗粒(GO/Ag)材料。各项材料学表征表明,制备的GO/Ag纳米复合颗粒中的银纳米粒子在GO片层中分布均匀,没有出现团聚的现象,粒径几乎均一,为40 nm左右。在以金黄色葡萄球菌为模型的抗菌实验中发现,GO/Ag纳米复合颗粒具有很强的杀菌效果,且对金黄色葡萄球菌的抑制性要明显强于GO。Graphite oxide was prepared via a modified Hummers method, and nontoxic green glucose was used as reducer to fabricate the graphene oxide/Ag nanoparticles composites. The results showed that the GO/Ag nanoparticles composites fabricated successfully and the Ag nanoparticles uniformly distributed in the graphene oxide sheets, the range of sizes of the Ag nanoparticles on the graphene sheets centralized at 40 nm. The antibacterial of the GO/Ag nanoparticles composites were studied with the staphylococcus aureus, and the results indicated that the GO/Ag nanopartieles composites had strong antibacterial effect, which were much better than GO.
