Abstract
In this study, vinyl-terminated polysiloxane (V-PDMS) had been prepared by ring-opening reaction, which was introduced as a monomer into polyacrylate emulsion via emulsion polymerization in order to obtain the acrylate-co-siloxane emulsion. The effect of V-PDMS content on the properties of the emulsion was investigated. Meanwhile, hydrochloric acid as catalyst and ethanol as dispersant, acidic silica sol had been prepared by the sol–gel method. Furthermore, the following three types of antireflection coatings were prepared. The first type of anti-reflection coating had been prepared by dipping a layer of copolymer emulsion on the substrate via the dip-coating method. Acidic silica sol and copolymer emulsion were sequentially dip-coated on the substrate in order to obtain the second type of anti-reflection coating, and the second type of anti-reflection coating was calcined to obtain the third type of anti-reflection coating. The effect of the interval time between two dips on the structure and light transmittance was investigated. The results show that the transmittance of the AR coating increases at the appropriate interval time. Among them, three types of antireflection coatings with different morphologies were prepared, each antireflection coating has a certain antireflection effect, and the highest transmittance can reach 94.5%.
