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.
The Sb2O3/mica nanoparticles were prepared by using layered mica as the microreaction 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, 8b2O3 nanoparticles assembled uniformly between mica layers, have a good dispersion property and a narrow size distribution around 5nm, 30nm less than that of 852O3 nanoparticles prepared without the addition of mica.
