摘要
在表面活性剂(聚乙烯吡咯烷酮、木质纤维素、聚乙二醇)的保护下,制备了纳米级的氯化银溶胶,借助于分光光度计和TEM分析仪研究了纳米氯化银在不同温度条件下的稳定性,同时对纳米氯化银的变色进行研究,用X射线衍射研究了纳米氯化银溶胶变色以后溶胶体系的变化。
Well-dispersed nanometer AgCl colloids are prepared through reaction of NaCI and AgNO3 in water liquor with the protection of polyvinypyrrolidone(PVP) ,PEG, and lignocellulose. The thermal stability of the AgCl colloids at different temperature are investigated by means of SEM and spectrophotometer and the composition of the colloids after colour-change is analyzed.
