梯度微纳米结构表面的液滴定向脱离
roplet shedding-off on gradient micro- and nanostructured surface
本文受蝴蝶翅膀表面液滴定向滚离的特性启发，通过机械微加工和水热合成法制备出了各向异性的超疏水表面。微米结构与纳米结构的复合使表面具有很大的空气占有比，又通过在表面真空蒸渡一层全氟硅烷获得很低的表面能，从而表面在低温时仍然处于Cassie状态，接触角稳定于150 和165 之间，具有良好的低温超疏水性。该表面的微米条纹锯齿结构两边倾斜角度的不同和规则的微米周期造就了液滴在该表面滚动的各向异性，液滴在样品表面更容易沿着倾斜角度小的方向滚动。
In this paper, we are inspired by the properties of the butterfly wings that the droplet directional rolled away on the surface. Then we obtain the superhydrophobic surface by micro mechanical processing and hydrothermal growth method. At low temperature, the droplet was still in cassie state because of the micro/nano-structure and the low surface energy, and the contact angle was stabilized between 150 to 165 . In addition, the surface had very good anisotropy. This was because the angles on both sides of the micro-structure were different. The droplets were more likely to roll along the direction of the tilt angle which is smaller.
