摘要
Abstract
Silica nanoparticles with different sizes were fabricated via the Stober method by adjusting the reaction temperature and the volumes of ethanol and water. Simple and convenient spraying-coating method was used to construct coatings on slide glasses with synthesized silica nanoparticles of 20 nm in size. Adhesion of silica nanoparticles to slide glasses was enhanced by calcination of the silica nanoparticle coatings at 550℃. After surface modification with 1H, 1H, 2H, 2H-perflurooctyltriethoxysilane, the wetting properties of these coatings changed from hydrophilicity to hydrophobicity. The silica nanoparticle coatings constructed by spray-coating are anti-reflective. When the mass percentage of silica nanoparticles was 0. 48 % and the number of spray-coating cycles was 3, the transmittance of coating reached as high as 95. 5% in the visible range. It was found by scanning electron microscopy observations that the coatings obtained by spray-coating are uniform and controllable. The spray-coating approach to the construction of nanoparticle coatings are a simple and fast fabrication process, and is suitable for large area applications.关键词
