摘要： 以片状云母作为微反应器制备了纳米Sb2O3/云母复合物, 并用XRD、TEM进行了表征. 研究了表面活性剂对纳米Sb2O3颗粒、纳米Sb2O3/云母复合物的粒子性能及粒度分布的影响, 并对二者进行了比较. 结果表明: 纳米Sb2O3被十六烷基三甲基溴化铵处理后, 在云母层间均匀生长, 形成的纳米Sb2O3分散性好, 粒度分布窄. 平均粒径约为5nm, 比不加云母制备的纳米Sb2O3小30nm.

Abstract: The Sb2O3/mica nanoparticles were prepared by using layered mica as the micro-reaction cell and characterized by means of XRD and TEM. The effects of
surfactants on the particle properties and particle-size distributions for both nano-Sb2O3 and Sb2O3/mica nanoparticle were investigated and compared. The results show that after modified by CTAB, Sb2O3 nanoparticles assembled uniformly between mica layers, have a good dispersion property and a narrow size distribution around 5nm, 30nm less than that of Sb2O3 nanoparticles prepared without the addition of mica.

Key words: Sb2O3, nanoparticle, mica, surfactant
