中文摘要：

采用化学还原法在氧化石墨烯（GO）表面负载纳米银（nAg）,制备纳米银-氧化石墨烯复合抗菌材料（GO-nAg）。透射电子显微镜（TEM）和X射线能量色散谱（EDS）表征结果表明,纳米银成功地负载在GO表面,纳米银分散良好。以大肠杆菌为目标细菌,对GO-nAg、纳米银以及GO的抗菌活性进行比较,实验结果表明,GO-nAg未表现出很强的抗菌性,且与纳米银抗菌效果基本一致,而GO抗菌效果更好。

英文摘要：

Nano-Ag（nAg）was deposited on graphene oxide（GO）by chemical reduction method to synthesize graphene oxide-silver nanocomposite（GO-nAg）,whose morphology and composition were characterized by transmission electron microscopy（TEM）and X-ray energy dispersive spectroscopy（EDS）,which proved that nAg were well deposited on the surface of GO.Escherichia coli（E.coli）was used to comparatively study the antibacterial ability of GO-nAg,nAg and GO.Experiment results indicated GO-nAg didn′t display great antibacterial activity（almost equal to that of nAg）,while GO exhibited a relatively strong antibacterial activity.
