| 摘 要： | 纳米SiO2粒子具有极大的比表面积和表面能,因而极易团聚,致使其在应用中无法发挥纳米粒子的优异性能,通过对纳米粒子表面改性可改善这一状况。纳米粒子表面改性的方法有:酯化法、偶联剂法、表面活性剂法、接枝聚合法、高能法等。改性后的纳米SiO2,因其独特的物理、化学、光学等性能在功能材料、塑料、橡胶、涂料及生物医药等方面得到广泛的应用。

| Abstract: | The nano-SiO2particles with great specific surface area and surface energy are very easy to aggre-gate,and the aggregated particles were hard to exert its excellent performance in use.To modify onto the sur-face of nano-SiO2could improve its condition.The means are as followings: esterifying agent modification,coupling agent modification,surfactant modification,graft polymerization modification,high power modifica-tion and so on.After modification,the nano-SiO2would have some particular physical,chemical,optical performance,so it was widely used in many fields,such as functional materials,plastics,rubbers,paints,biomedicine,etc. |
