利用193 nm ArF准分子激光诱导硅橡胶表面形成的周期性微溶胀结构,在硅橡胶表面形成具有超疏水特性的织构Al薄膜。通过扫描电子显微镜和原子力显微镜观察到,在真空蒸发过程中,仅在硅橡胶衬底上的Al薄膜发生了自动织构化,而在载玻片或硅树脂衬底上的Al薄膜发生了自动织构化。结果,在两种情况下,水在具有10 nm和30 nm厚的织构化Al薄膜的样品上的接触角估计为约162°,而没有Al的样品为约155°。此外,一个大的空气间隙显着形成之间的Al沉积的样品和水;一滴有色水被成功地限制在空气间隙中,它被释放到水中时,需要的地方。
Silicone rubber, which is widely used in electrical and biomedical applications, was modified into superhydrophobic property by the formation of a textured Al thin film on the periodic microswelling structure fabricated on silicone rubber by the 193 nm ArF excimer laser-induced photodissociation of silicone. The texturing of Al thin film occurred automatically during the vacuum evaporation only on the silicone rubber, compared with the cases of a slide glass or silicone resin substrate, which were observed by the scanning electron microscope and atomic force microscope. As a result, contact angle of water on the samples with 10- and 30-nm-thick, textured Al thin films was estimated to be approximately 162° in both cases, compared to the sample without Al of approximately 155°. Moreover, a large air gap was remarkably formed between the Al-deposited sample and water; a droplet of colored water was successfully confined in the air gap and it was released into the water when and where need.
