以乙二醇为溶剂和还原剂，采用水热法制备了ZnO纳米颗粒修饰的广溶性单层石墨烯（FLG）薄膜。采用x射线衍射（XRD）、透射电子显微镜（TEM）和拉曼光谱对制备的FLG/ZnO复合材料进行了表征。采用孔扩散法研究了多层石墨烯修饰ZnO纳米颗粒对大肠杆菌和伤寒沙门氏菌的抑菌性能。结果表明，FLG/ZnO对伤寒沙门氏菌的抑菌活性高于大肠杆菌。目前的研究结果表明，用少量层状石墨烯修饰的ZnO纳米粒子具有显著的抗菌活性。(C) 2015 Elsevier Ltd.版权所有。
A widely soluble few layered graphene (FLG) sheets decorated by ZnO nano particles were prepared through hydrothermal method using ethylene glycol as a solvent and a reducing agent. The obtained FLG/ZnO composite material was characterized by X-ray diffraction (XRD), Transmission electron microscopy (TEM) and Raman spectroscopy. The anti-bacterial properties of ZnO nano particles decorated few layered graphenes were tested against Escherichia coil and Salmonella typhi by using well diffusion method. The results confirmed that FLG/ZnO has significant antibacterial activity more against S. typhi than E. coll. The obtained results from the current research work conclusively states that the ZnO nano particles which were decorated by few layered graphene possess a significant anti-bacterial activity.
