摘要/Abstract

摘要： 以常用工程材料硅树脂BP与Stöber法合成的二氧化硅(SiO₂)分散液为原料,运用喷涂法(spray-coating)制备出了功能性微/纳粗糙(MNR)结构的超疏水涂层,其接触角可以达到146.5°,滚动角小于1°(测试液滴量为15 μL).通过分析喷涂法制备复合涂层所需的条件,得出喷涂液pH=7.7-8.0时,在适当的硅树脂BP/SiO₂配比条件下,复合涂层表面形成了与荷叶表面类似的MNR结构.随着SiO₂含量的增加,MNR复合涂层表面类球状突起小球的体积有增大的趋势.结合硅树脂BP的低表面能,MNR复合涂层具备了超疏水性,且复合涂层具备良好的耐腐蚀和耐老化性能.

Abstract: Common engineering materials silicone BP and silica (SiO₂) dispersions synthesized by the Stöber method were used to prepare functional micro/nano rough (MNR) superhydrophobic composite coatings by spray-coating. The water contact angle of the composite coatings could reach 146.5, and the sliding angle was less than 1 (the volume of test droplet is 15 μL). The conditions of spray-coating process were discussed, and under the conditions of pH=7.78.0 and suitable silicone BP/SiO₂ mass ratio of spraying solution, the MNR composite coating could be formed, which is similar to the lotus leaf surface micro/nano hierarchical structure. The micrometer papilla sizes on the MNR composite coating surface increase with increase of the SiO₂ content. Combined with the low surface energy of silicone BP, the MNR composite coating became superhydrophobic with anti-corrosion and anti-aging properties.

Key words: spray-coating, silicone, composite coating, superhydrophobicity, micro/nano hierarchical structure, contact angle, sliding angle
