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粒子表面电荷的性质,采用加入表面活性剂,在其表面形成碳氧链向外伸展的包覆层,以避免粉体的硬团聚。通过实验证明:0.70%三乙醇胺对浓度为5%纳米ZnO悬浮液具有良好的稳定作用。
Because of the especial domino effect,the nano- ZnO particle would be reunited during the using,so the nano- ZnO was limited. Some surfactants can come into being the layer that can keep from nano- ZnO Sreuniting. The experiment concludes that 0.70 % ethanolamine can force stabilization on the liquor of nano- ZnO.
