中文摘要:
      目的 研究石墨烯/银纳米粒子(AgNP/G)复合抗菌材料简单快捷的制备方法。方法 在碱性环境下采用原位还原法制备AgNP/G纳米复合材料。利用X射线衍射、红外、紫外和透射电镜等技术对AgNP/G复合材料的结构及形貌进行表征,探讨其形成机理,并通过平板计数法来观察AgNP/G复合材料的抗菌性能。结果 所制备的AgNP/G复合材料中,形成的纳米银尺寸较小(15 nm)、粒径均一,在石墨烯片层上分布均匀。当AgNP/G的抗菌质量浓度为20 μg/mL时,抗菌率达到98.7%。结论 碱的存在能加速银纳米粒子在石墨烯片层上的形成,得到的AgNP/G复合材料抗菌性能优异。
英文摘要:
      The work aims to study the simple and quick methods used to prepare graphene/silver nanoparticle (AgNP/G) composite antimicrobial materials. AgNP/G nanocomposite was prepared in the alkaline environment in in-situ reduction method. The structure and morphology of AgNP/G composites were characterized by X-ray diffraction, infrared, ultraviolet and transmission electron microscopy. The formation mechanism of AgNP/G composites was investigated. The antimicrobial properties of AgNP/G composites were observed by plate counting method. In the prepared AgNP/G composite, the nano-silver formed was small in size (15 nm), uniform in particle size, and evenly distributed on the graphene sheet. When the antimicrobial concentration of AgNP/G was 20 μg/mL, the antibacterial rate could reach 98.7%. The presence of alkali can accelerate the formation of silver nanoparticles on the graphene sheet, and the prepared AgNP/G composite has excellent antibacterial properties.
