摘　　要：由于纳米粒子的特殊效应,使其在实际生产中不可避免地出现团聚现象,从而影响纳米材料的使用范围。根据纳米ZnO粒子的特点,采用加入烷基二苯醚双磺酸钠表面活性剂,在其表面可产生静电的、溶剂化的和空间稳定的防止聚集的作用,避免粉体的硬团聚。实验证明:烷基二苯醚双磺酸钠对纳米ZnO分散性优于十二烷基硫酸钠,这两种表面活性剂复配后分散效果更佳,且在水中最佳分散条件分别为:0.8%混和表面活性剂2、.0%纳米ZnO、pH值为9。Because of the especial domino effect, the nano - ZnO particle would be reunited during the using, the nano - ZnO was limited. Some surfactants came into being the layer that could keep from nano - ZnO＇ s reuniting. The results indicated that the best dispersants was mixed surfactants and the best dispersion conditions of nano - ZnO in aqueousadding were 0.8 % mixed surfactants and at pH = 9.
