Slippery liquid-infused porous surfaces (SLIPS) for anti-icing

Abstract

Slippery liquid −infused porous surfaces (SLIPS) have received significant attention for their potential to address icing safety and deicing energy challenges. In order to overcome the bottlenecks due to inconsistencies in evaluation methods and durability issues. The mechanism research of SLIPS has been discussed from wettability until anti-icing and deicing, and the related evaluation methods are organized. Moreover, the performance characteristics, preparation processes and key research results of various SLIPS materials are summarized. Further, three SLIPS durability enhancement approaches are proposed as the focus of this paper, including structural engineering of the substrate, lubricant immobilization, and supplementation strategies. Finally, current key issues are summarized and potential application scenarios are envisioned, which are inspiring for subsequent interdisciplinary research and engineering translation of SLIPS.
