摘　　要：纳米SiO2粒子被广泛用作填料来改性聚合物。但纳米SiO2粒子极易发生团聚,在有机介质中难以均匀分散,使其在许多领域的应用和发展受到限制。对纳米SiO2粒子进行表面改性处理,可以使之较好地分散到有机介质中。纳米SiO2粒子有多种表面改性方法,其中以聚合物包覆的方法效果最好。本文综述了纳米SiO2表面聚合物改性的一般方法,并对其应用前景进行了展望。Nano-SiO2 particles have been widely used as filler for modifying polymer.But the Nano-SiO2 particles agglomerated easily and dispersed diffcult in organic solvents,so the application and development of Nano-SiO2 is limited in some fields.Nano-SiO2 particles could disperse into the organic media better after surface modification treatment.There are a variety of methods for surface modification of Nano-SiO2 particles,in which the polymer coating method is the better.The general methods of polymer-modified of nano-SiO2 surface have been reviewed,and the prospects of their applications have been predicted.
