| 中文摘要: |
| 用改进的Hummer法制备了氧化石墨烯(GD),并制备 了表面用聚乙烯吡咯烷酮修饰的纳米银线(AgNWs), 通过原位还原法将二者复合成一种新型的水溶性AgNWs/还原石墨烯(RGD)材料,克服了石 墨烯材料不易分散 的缺点。用X射线衍射(XRD)、紫外-可见分光(UV-vis)光度计、扫描电子显 微镜(SEM)和傅里 叶变换红外(FT-IR)光谱分析仪对样品结构和形貌进行了表征。结果表明,制备的AgNWs/RG D材料具有与前驱 体不同的物理参数,有望在非线性光学、光电传感器和生物抑菌等方面有良 好的表现。 |
| 英文摘要: |
| Graphene oxide (GO) was prepared with an improved method which refers to the Hum mer method,then the silver nanowire was surface modified in situ with polyvinyl pyrrolidone,and the graphene composited silver nanowire materials were prepared latter,which can disperse well in aqueous solu tion.This characteristic of the material is conducive to the further research and i ts application.X ray diffraction (XRD) experiment,ultraviolet visible spectropho tometer (UV-vis),scanning electron microscope (SEM) and Fourier transform infrared (FT-IR) spectroscopy analyzer were used for the characteriza tion of the samples.Results show that the reduction of graphene composited silver nanowires has ne w different physical characterization parameters with the precursor.The characteristic diffr action peaks in XRD pattern of this compound have been found,the absorption spectra show obvi ous peak different from the precursor,and the FTIR image of this material has given an evidence of the link between the modified silver nanowire and the graphene,that is the amide II vibration between nitrogen atoms and carbon atoms at 1535cm－1.This material may have good performance in nonlinear optics,photoelectric sensor and biological antibac terial fields. |
