LIQUID-IMPREGNATED SURFACES WITH ENHANCED DURABILITY

摘要

Embodiments described herein relate generally to devices, systems and methods for producing liquid impregnated surfaces with enhanced durability. In some embodiments, a liquid-impregnated surface includes a first surface having a first roll off angle. A plurality of solid features are disposed on the first surface, such that a plurality of interstitial regions are defined between the plurality of solid features. An impregnating liquid is disposed in the interstitial regions. Furthermore, the interstitial regions are dimension and configured such that that the surface remains impregnated by the impregnating liquid. The impregnating liquid disposed in the interstitial regions defines a second surface which has a second roll off angle less than the first roll off angle. The apparatus also includes a liquid delivery mechanism configured to transfer the impregnating liquid to the interstitial regions.
