中文摘要：
采用油酸萃取并包覆AgCl纳米水溶胶粒子，制备了AgCl纳米有机溶胶，对有机溶胶的制备条件进行了系统的研究，获得了最佳的制备条件。对制得的AgCl纳米有机溶胶进行了表征。TEM分析表明，AgCl纳米粒子呈球形，粒径约50nm，粒径分布均匀，无明显团聚现象；ED分析表明，AgCl纳米粒子为多晶结构，其中有少量的单晶存在。表面包覆油酸的AgCl纳米粒子易分散于弱极性溶剂，难分散于极性溶剂，表明油酸对AgCl粒子进行了较好的包覆。
英文摘要：
AgCI organosol was obtained by using oleic acid to extract and modify the AgC1 nanoparticles in hydrosol, the influencing factors on organosol were discussed systematically, and optimum preparative conditions were obtained. TEM photos showed that the AgCl nanoparticles are sphere in shape, and the size is about 50 nm. Particle size distribution was in narrow range, and no obvious agglomerates were observed. ED images indicated that the AgCl nanoparticles have polycrystalline structure, and some of AgC1 were monocrystalline particles. AgCl nanoparticles coated with oleic acid were easily dispersed in weak polar solvents, but were not dispersed in polar solvents. This result indicated that the AgCl nanoparticles were well coated by oleic acid molecules.
