| 摘 要： | 本文综述了近几年国内外对纳米二氧化硅的表面化学修饰及其在聚合物基纳米复合材料中与基体作用方式的研究工作。对纳米SiO2进行表面修饰可以改善纳米颗粒与聚合物基体间的亲和性，同时可以使纳米SiO2表面功能化，有利于SiO2与聚合物基体间形成强的结合力。纳米SiO2与聚合物基体间可以以吸附力、氢键、共价键等方式结合，不同的结合方式对材料性能也会产生不同程度的影响。

| Abstract: | In this paper, the research on surface modification of nanosilica and its action mode with polymer are reviewed. After nanosilica is surface-modified, its compatibility with polymeric matrix is improved. In the mean time, the surface of nanosilica is functionalized, which is propitious for strong bonding force with polymer. The combining modes such as adsorption affinity, hydrogen bond and covalent bond can be formed between the silica and the polymeric matrix, which affect the performance of the formed nanocomposites. |
