Vibrating lubricant-infused porous surface for enhanced liquid droplet transport
Lubricant-infused porous surfaces (SLIPS) demonstrate extreme liquid repellency such that a droplet immiscible with the lubricant can roll off at a very small tilt angle < 5°. There have been many applications in using SLIPS to achieve complex fluids handling, anti-fouling, self-cleaning, …

Design and development of durable lubricant-infused surfaces for water shedding applications
Submission published under a 24 month embargo labeled 'U of I Access', the embargo will last until 2025-12-01

A Study of Dew Harvesting and Freezing Performance of Non-Wetting Surfaces
… water scarcity in water stressed areas. Slippery lubricant infused surfaces have the ability to shed water droplets with lower nucleation times, taking advantage of more of the limited amount of time available to collect dew and fog than traditional surfaces. However, existing studies focus on …

Studies on Corrosion, Fouling and Durability of Advanced Functional Nonwetting Surfaces
Superhydrophobic and lubricant-infused porous surfaces are two classes of non-wetting surfaces that are inspired by the adaptation of natural surfaces such as lotus leaves, pond skater legs, butterfly wings, and Nepenthes pitcher plant. This dissertation focuses on fabrication and in depth study of …

Dropwise condensation of water and low surface tension fluids on structured surfaces
… surface tension fluids. Recent development in lubricant infused surfaces (LIS) offers promising solutions to achieving dropwise condensation of low surface tension fluids by replacing the solid-condensate interface in conventional hydrophobic coatings with a smooth lubricant-condensate …

Experimental Investigations on Non-Wetting Surfaces
Superhydrophobic (SHS) and lubricant-infused surfaces (LIS) exhibit exceptional non-wetting characteristics that make them attractive for energy production applications including steam condensation and fouling mitigation. The dissertation work focuses on application of non-wetting surfaces to …

Droplet evaporation dynamics on surfaces
… developed including hydrophobic, biphilic and lubricantinfused surfaces. However, evaporation of droplets on these surfaces have not been explored in depth. Traditionally, evaporation on surfaces was characterized by observing the temporal size changes of a droplet. Yet, the transient nature …

Analysis of Interfacial Processes on Non-Wetting Surfaces
… mainly categorized into superhydrophobic (SHS), lubricant-infused (LIS) and solid-infused surfaces (SIS), by virtue of their superior water repellant properties have wide applications in several energy and environmental systems. In this dissertation, the role of non-wetting surfaces toward the …

Enhanced condensation heat transfer for water and low surface tension fluids
… often form a film, even on hydrophobic coatings. Lubricant infused surfaces (LIS) represent a potential solution, where a lubricant immiscible with the low surface tension condensate is infused into a rough structure on the condenser surface to repel the condensate. We developed a detailed …

Progress Toward Durable Icephobic Materials
… including the stabilization of slippery lubricant-infused porous surfaces (SLIPS) via polymer cross-linking at the interface, copolymerization of commercial poly(dimethylsiloxane) resins with acrylate / styrene monomers yielding highly cross-linked network copolymer coatings, and lowering …

YIELDING PHENOMENA IN MICROGEL SUSPENSIONS ACROSS LENGTH SCALES
… surfaces. We studied Carbopol droplets on lubricant-infused substrates, identifying regimes of sliding and rolling based on droplet concentration and surface inclination. A simple criterion based on the ratio between yield and gravitational stresses distinguished sliding from rolling …
