摘要
以具有不饱和双键的油酸为表面活性剂，对水溶胶中的ＣｅＯ２纳米粒子进行表面修饰。ＴＥＭ分析表明，经表面修饰的ＣｅＯ２纳米粒子基本呈球形，粒径约为３ｎｍ，分布均匀；并且表面包覆油酸的ＣｅＯ２纳米粒子易溶于弱极性溶剂，不易溶于极性溶剂。
CeO2 nanoparticls which are in the hydrosol were modified by oleic acid with unsaturated double bonds surfactant. TEM analysis shows that CeO2 nanoparticles coated with oleic acid are spherical in shape. The average size of the particles is 3nni. Moreover, CeO2 nanoparticles coated with oleic acid are easy to dissolve in weak polar solvent, not in polar solvent.
