Abstract
Losing contact: Omniphobic surfaces can be readily produced by acid-catalyzed graft polycondensation of dimethyldimethoxysilane (PDMS). Droplets show a very small contact angle hysteresis as well as a low sliding angle of only a few degrees. The nm-thick PDMS layer is neither easily washed away nor depleted. This method offers a novel approach towards the preparation of super-liquid-repelling surfaces.

通过酸催化接枝缩聚二甲基二甲氧基硅烷（PDMS）可以很容易地制备出全疏水性表面。液滴表现出非常小的接触角滞后和仅几度的低滑动角。厚度为纳米级的 PDMS 层既不容易被洗掉也不容易耗尽。这种方法为制备超疏液表面提供了一种新的途径。
