我们报告了一种简单而廉价的方法，通过直接复制微/纳米结构上的聚二甲基硅氧烷（PDMS）从超快激光微织构工艺制备的复制母版。在PDMS上不需要额外的涂层来实现大于154度的接触角。接触角可以通过改变PDMS中微织构的高度来控制。微/纳米纹理表面的极低光学反射特性与超疏水特性相结合，使其成为光致发光和其他应用的有吸引力的封装材料。此外，该复制方法可用于大规模生产用于商业应用的微/纳米纹理化超疏水表面。(C)2012爱思唯尔有限公司版权所有。
We report a simple and inexpensive method of producing superhydrophobic surfaces by directly replicating micro/nano-structures on to poly(dimethylsiloxane) (PDMS) from a replication master prepared by ultrafast-laser microtexturing process. No additional coatings on PDMS have been required to achieve contact angles greater than 154 degrees. The contact angle can be controlled by changing the height of the microtextures in PDMS. Very low optical reflection properties of micro/nano textured surfaces combined with superhydrophobic characteristics make it an attractive encapsulating material for photovoltaics and other applications. Additionally, this replication method can be applied for large scale production of micro/nano textured superhydrophobic surfaces for commercial applications. (C) 2012 Elsevier B.V.
