Liquid Infused Surfaces with Anti-icing Properties
Ice accretion on solid surfaces, a ubiquitous phenomenon occurring in winter, is able to bring much inconvenience to our daily-life and even can cause serious catastrophe. Icephobic surfaces, a passive way via processing surfaces to prevent surfaces destruction from ice accumulation, have attracted much attention of scientists since its special ice-repellent property, and many efforts have been spent to rationally design durable icephobic coating. This review is aimed at providing a brief and crucial overview of ice formation process and feasible de-icing strategies. Here, the excellent anti-icing performance of liquid infused surfaces (LIS) inspired from Nepenthes was emphatically introduced. After a short introduction, the recent processes of ice nucleation theory and decrease ice adhesion mechanism were comprehensively reviewed to gain a general understanding of the long freeze process and low ice adhesion on LIS. Subsequently, the anti-icing performance of LIS was systematically evaluated from four aspects regarding water repellence, condensation-frosting, long freeze process, and low ice adhesion. Finally, this review focused on discussing the advantages and disadvantages of LIS and the potential measures to eliminate and alleviate these drawbacks.
