摘 要: 聚乙二醇或聚乙二醇和水作溶剂,制备出银纳米颗粒和纳米级银链;用红外光谱(IR)、X-射线粉末衍射(XRD)和透射电子显微镜(TEM)测试手段对其结构和形貌进行了表征,并分析银纳米链的形成机理. Silver nanoparticles and Silver nanochains were successfully prepared by using polyethylene glycol (PEG) as solvent or PEG and water as mixed solvent. The structure and shape were characterized by transmission electron microscope (TEM), infrared spectroscopy (IR), x-ray powder diffraction (XRD), and the presumable formation mechanism was ratiocinated.
