Fundamentals of Icing and Common Strategies for Designing Biomimetic Anti-Icing Surfaces

Abstract

Ice accumulation on solid surfaces can incur irretrievable loss and catastrophic affairs in daily life. These issues can be addressed and alleviated strategically with proper methods adopted. Compared with conventional deicing strategies, such as electro-impulse, chemical method and mechanical deicing approach, passive anti-icing and ice-phobic surfaces inspired by nature animals and plants have been manifested exceedingly profound advantage. Herein, the kinetics of ice nucleation on solid surfaces and heat transformation during ice formation are investigated first. Then, the reducing attachment pathway of water droplets on substrate surfaces are reviewed for the purpose of achieving water droplets self-removal and averting wettability transition on superhydrophobic surfaces. Furthermore, special attention is poured into recent biomimetic anti-icing strategies regarding reduction of ice adhesion, decrease of ice nucleation temperature and delay of freeze time. Significantly, other external factors, such as environmental humidity and exoteric gas flow, affecting ice formation and growth are comprehensively discussed. Finally, outstanding mechanical and chemical stability are vital for lengthening durability and longevity of anti-icing/ice-phobic surfaces. All of these matters and outlooks for future research directions of anti-icing and ice-phobic are also revealed in this article.
