纳米氯化银溶胶的制备及其热稳定性研究

Synthesis and Thermal Stability of Nano-AgCl

    摘要
  • 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。

     

    Abstract: Well-dispersed nanometer AgCl colloids are prepared through reaction of NaCl 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.
