Abstract: The present disclosure describes a strategy to create self-healing, slippery liquid-infused porous surfaces (SLIPS). Roughened (e.g., porous) surfaces can be utilized to lock in place a lubricating fluid, referred to herein as Liquid B to repel a wide range of materials, referred to herein as Object A (Solid A or Liquid A). SLIPS outperforms other conventional surfaces in its capability to repel various simple and complex liquids (water, hydrocarbons, crude oil and blood), maintain low-contact-angle hysteresis (<2.5°), quickly restore liquid-repellency after physical damage (within 0.1-1 s), resist ice, microorganisms and insects adhesion, and function at high pressure (up to at least 690 atm). Some exemplary application where SLIPS will be useful include energy-efficient fluid handling and transportation, optical sensing, medicine, and as self-cleaning, and anti-fouling materials operating in extreme environments.

Abstract: A technique relates to a nanogap array. A substrate has been anisotropically etched with trenches that have tapered sidewalls. A sacrificial layer is on bottoms and the tapered sidewalls of the trenches. A filling material is formed on top of the sacrificial layer in the trenches. Nanogaps are formed where at least a portion of the sacrificial layer has been removed from the tapered sidewalls of the trenches while the sacrificial layer remains on the bottoms of the trenches. Each of the nanogaps is formed between one tapered sidewall of the substrate and a corresponding tapered sidewall of the filling material. The one tapered sidewall of the substrate opposes the corresponding tapered sidewall. A capping layer is disposed on top of the substrate and the filling material, such that the nanogaps are covered but not filled in.
