Nano-silica was modified by dimethyldichlorosilane. The modified nano-silica was characterized by infrared spectroscopy, laser nano-particle size analyzer. The influence of modified nano-silica on the performance of holographic coatings was studied by scanning electron microscopy (SEM) and contact angle measurement instrument. The results showed that the modified nano-silica possessed excellent lipophilic performance and good dispersivity in holographic coatings and the hydrophobic performance, heat-resistance, wear-resistance and diffraction efficiency of the holographic coatings were improved when the content of nano silica was 2%.Keywords:  Nano-silica, Holographic Coatings, Modify, Lipophilic
