通过193 nm ArF准分子激光诱导光解在硅橡胶表面形成周期性微膨胀结构，在硅橡胶表面涂覆一层50 nm厚的织构Al薄膜，以实现与水的接触角约165度的超疏水。与石英玻璃或硅树脂衬底相比，仅在硅橡胶衬底上通过真空蒸发自动获得了织构Al薄膜。结果表明，涂铝有机硅与水之间形成了较大的气隙，即使在3wt%的氯化钠水溶液中，也能在表面施加5V/mm的电场。(C)2018年日本应用物理学会
A periodic microswelling structure on silicone rubber fabricated through 193 nm ArF excimer laser-induced photodissociation was coated with a 50-nm-thick, textured Al thin film to realize the superhydrophobicity of approximately 165 degrees of contact angle of water. The textured Al thin film was obtained automatically during vacuum evaporation only on the silicone rubber, compared with a silica glass or silicone resin substrate. As a result, a large air gap layer was formed between the Al-coated silicone and water; an electric field of 5 V/mm could be applied to the surface of the Al-coated silicone even in 3 wt% NaCl aqueous solution.
