The accumulation of ice will reduce the performance of the base material and lead to all kinds of damage, even a threat to people's life safety. Recent increasing studies suggest that superhydrophobic surfaces (SHSs) originating from nature can remove impacting and condensing droplets from the surface before freezing to subzero temperatures, and it can be seen that hydrophobic/SH coating has good freezing cold resistance. But such anti-icing performances and developments in practical applications are restricted by various factors. In this paper, the mechanism and process of surface icing phenomenon are introduced, as well as how to prevent surface icing on SHS. The development of SH materials in the aspect of anti-icing in recent years is described, and the existing problems in the aspect of anti-icing are analyzed, hoping to provide new research ideas and methods for the research of anti-icing materials.
冰的积累会降低基材的性能并导致各种损坏,甚至对人们的生命安全构成威胁。最近越来越多的研究表明,源自自然界的超疏水表面(SHS)可以在液滴冻结至零下温度之前将撞击和冷凝的液滴从表面去除,由此可见疏水/超疏水涂层具有良好的抗冻性。但这种抗冰性能及其在实际应用中的发展受到各种因素的限制。本文介绍了表面结冰现象的机理和过程,以及如何防止超疏水表面结冰。描述了近年来超疏水材料在抗冰方面的发展,并分析了抗冰方面存在的问题,希望为抗冰材料的研究提供新的研究思路和方法。
