Abstract:
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.
Abstract:
Embodiments described herein relate generally to a system and methods for controlling and/or modifying the degradation behavior of degradable materials via a surface treatment and/or coating. This surface treatment and/or coating (also referred to herein as a “barrier”) can be used to modify the degradation profile without changing the bulk of the degradable material. The system includes a substrate that includes a degradable material and barrier configured to protect the substrate from a foreign environment. The barrier can include a conformal coating and/or a liquid impregnated surface engineered specifically to tailor the degradation profile of the underlying substrate. Optionally, a trigger mechanism can be used to further control and/or modify the degradation behavior of the substrate.
