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.
