【摘要】 采用沉淀法制备了CuO水溶胶 ,用油酸萃取并包覆CuO纳米水溶胶 ,制备了CuO纳米有机溶胶 ,对有机溶胶的制备条件进行了系统地研究。由TEM分析表明 ,有机溶胶中CuO纳米粒子呈球形 ,粒径约为 2 0nm ,粒子分布均匀 ,无明显团聚现象。更多还原

【Abstract】 The CuO hydrosol was prepared by the precipitation method, the organosols of CuO was obtained by using oleic acid to extract and modify the nanoparticles in hydrosol, the effect factors on organosol were discussed systematically.TEM photos showed that the CuO nanoparticles were sphere in shape, the size is about 20nm, particle size distribution was in narrow range, and no agglomerates were observed.更多还原
