Influence of Modified Nano-Silica on the Performance of Laser Holographic Coatings

摘要

Nano-silica was modified by dimethyldichlorosilane. The modified nano-silica was added to the acrylate resin in order to improve the performance of holographic coatings. 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 good dispersivity in holographic coatings. The hydrophobic performance, heat-resistance, wear-resistance and diffraction efficiency of the holographic coatings were improved when the content of nano silica was 2%.
