    摘要:

    采用沉淀法制備了AgCl與Cu^2 共存的納米水溶膠，油酸萃取并包覆AgCl與Cu^2 共存的納米水溶膠，制備了AgCl與Cu^2 共存的納米有機(jī)溶膠，對水溶膠和有機(jī)溶膠的制備條件進(jìn)行了系統(tǒng)的研究。TEM分析表明，AgCl納米粒子呈球形，粒徑約50nm，粒度分布均勻，無明顯團(tuán)聚現(xiàn)象。ED分析表明，AgCl納米粒子為多晶結(jié)構(gòu)，其中有少量的單晶存在。表面包覆油酸的AgCl納米粒子易溶于弱極性溶劑，難溶于極性溶劑。

    Abstract:

    A hydrosol of coexisting AgCl and Cu2+ was prepared by the precipitation method. The organosol of coexisting AgCl and Cu2+ was obtained by using oleic acid to extract and modify the nanoparticles in hydrosol, TEM photos showed that the AgCl nanoparticles were spherical in shape, and about 50nm in size. The particle size distribution was narrow and no agglomerates were observed. ED imaging indicated that the AgCl nanoparticles were polycrystalline in structure, and some of AgCl existed as monocrystalline particles. AgCl nanoparticles coated with oleic acid easily dissolved in weak polar solvents, but would not dissolve in polar solvents.
