摘要
以聚丙烯酸铵为保护剂,利用液相化学还原法成功的制备了纳米银颗粒。利用透射电子显微镜(TEM),X射线衍射(XRD)对样品的形貌和结构进行了分析,并讨论了聚丙烯酸铵的加入量对纳米银粒径的影响。利用紫外分光光度计(UV光谱)对纳米银溶胶的粒径分布及其稳定性进行了分析。研究结果表明,聚丙烯酸铵的加入量对纳米银的粒径和形貌有重要的影响。同时,所制备的纳米银溶胶的稳定性较好。
Silver nanoparticles with narrow distribution were prepared by a simple route in water in presence of poly-acrylic acid ammonium as the capping agents.The morphology and crystal structure of as-synthesised silver nanoparticles were analyzed by transmission electron microscopy and X-ray powder diffraction.Moreover,the effect of the amount of poly-acrylic acid ammonium on the morphology and size of the silver nanoparticles was discussed.The size distribution and the stability of as-synthesized silver nanosol was analyzed by the UV-vis spectrophotometer.The results showed that the poly-acrylic acid ammonium played an important role for the morphology and size distribution of silver nanopaticels.The stability of t nanosol was perfect.
