AgI纳米有机溶胶的制备与表征

Preparation and Characterization of AgI Nanoparticle Organosol

采用油酸萃取并包覆AgI纳米水溶胶,制备了AgI纳米有机溶胶,对有机溶胶的制备条件进行了系统的研究。TEM分析表明,AgI纳米粒子呈球形,粒径小于50 nm,粒度分布均匀。表面包覆油酸的AgI纳米粒子易溶于弱极性溶剂,难溶于极性溶剂。

The organosol of AgI was obtained by using oleic acid to extract and modify the nanoparticles in hydrosol, the effect factors on organosol were discussed systematically. TEM photos show that the AgI nanoparticles were sphere in shape, particle the size was less than 50nm, the particle size distribution was in a narrow range, and no agglomerates were observed. AgI nanoparticles coated with oleic acid easily dissolve in weak polar solvents, but could not dissolve in polar solvents.
