Icephobic Behavior of UV-Cured Polymer Networks Incorporated into Slippery Lubricant-Infused Porous Surfaces: Improving SLIPS Durability

Abstract

Ice accretion causes damage on power generation infrastructure, leading to mechanical failure. Icephobic materials are being researched so that ice buildup on these surfaces will be shed before the weight of the ice causes catastrophic damage. Lubricated materials have imposed the lowest-recorded forces of ice adhesion, and therefore lubricated materials are considered the state-of-the-art in this area. Slippery lubricant-infused porous surfaces (SLIPS) are one type of such materials. SLIPS are initially very effective at repelling ice, but the trapped fluid layer that affords their icephobic properties is easily depleted by repeated icing/deicing cycles, even after one deicing event. UV-cured siloxane resins were infused into SLIPS to observe effects on icephobicity and durability. These UV-cured polymer networks enhanced both the icephobicity and longevity of the SLIPS; values of ice adhesion below 10 kPa were recorded, and appreciable icephobicity was maintained up to 10 icing/deicing cycles.

A Novel Simple Anti-Ice Aluminum Coating: Synthesis and In-Lab Comparison with a Superhydrophobic Hierarchical Surface

“…The SLS evidenced an even higher ARF than the SHP. This remarkable result is comparable to the shear stress values of several SLIPS coatings [28,38,54,55].…”

“…The SLS evidenced an even higher ARF than the SHP. This remarkable result is comparable to the shear stress values of several SLIPS coatings [28,38,54,55]. Both superhydrophobic and slippery surfaces evidenced a good reduction of ice adhesion with respect to the bare aluminum alloy; noteworthy, the SLS has better ice-phobic properties.…”

Highly cross‐linked UV‐cured siloxane copolymer networks as icephobic coatings

“…The maximum measured intensities of UVA, UVB, and UVC for this source were 890, 820, and 200 mW cm −2 , measured with a Power Puck II from EIT Inc. Self‐supporting films for swelling experiments were prepared using the same equipment but were cured in a poly(tetrafluoroethylene) mold, yielding ingots approximately 10 × 30 × 2 mm in size. Ice adhesion measurements were carried out in the Cold Weather Biome at Western's Biotron Facility using our previously described centrifuge method . Material hardness was measured with a Micro Materials Nano Test Machine equipped with a Berkovich Indenter.…”

“…In regard to the function, SLIPS represent a single system which can meet the multifunctional requirements with anti‐icing and anti‐corrosion. In pursuing this line of research, a number of methods for preparing SLIPS to improve the corrosion resistance and anti‐icing performances have been studied . For example, Guo et al.…”
