“…The ice adhesions reach 16.7 and 7.3 kPa at the structure volume fractions of the nano-pillar of 4.5% and 71.7%, respectively, which are generally recognized as ultra-low ice adhesion strength [22,40]. The tendency of the results is similar to that obtained by micro-column arrays on silicon wafer [41], which implies a strong connection between micro-and nano-structured surfaces. The variation in ice adhesion strength shows a similar trend with the previously measured contact angle, which is correlated with the structure volume fraction of the nano-pillar arrays on the epoxy resin surface, as shown in Figure 8.…”

Ice accumulation on wind turbine blades reduces power generation efficiency and increases wind turbines’ maintenance cost, even causing equipment damage and casualties. In this work, in order to achieve passive anti-icing, a series of nano-pillar array structures with different diameters of from 100 to 400 nm and heights of from 400 to 1500 nm were constructed on the substrate bisphenol-A epoxy resin, which is generally used in the manufacturing of wind turbine blades. The as-constructed functional surface showed excellent water repellence, with a contact angle of up to 154.3°. The water repellence on the nano-pillar array structures could induce ultra-low ice adhesion as low as 7.0 kPa, finding their place in the widely recognized scope of icephobic materials. The underlying solid–ice interface mechanism was well revealed in regard to two aspects: the interface non-wetting regime and the stress concentration behavior on the nano-pillar array structured surface. A detailed discussion on both the factors presented here will help surface structure design and function of icephobic materials, especially for epoxy-based composite materials.

In numerous fields such as aerospace, the environment, and energy supply, ice generation and accretion represent a severe issue. For this reason, numerous methods have been developed for ice formation to be delayed and/or to inhibit ice adhesion to the substrates. Among them, laser micro/nanostructuring of surfaces aiming to obtain superhydrophobic behavior has been taken as a starting point for engineering substrates with anti-icing properties. In this review article, the key concept of surface wettability and its relationship with anti-icing is discussed. Furthermore, a comprehensive overview of the laser strategies to obtain superhydrophobic surfaces with anti-icing behavior is provided, from direct laser writing (DLW) to laser-induced periodic surface structuring (LIPSS), and direct laser interference patterning (DLIP). Micro-/nano-texturing of several materials is reviewed, from aluminum alloys to polymeric substrates.

“…Logically, if a given functional material pretends to be icephobic, it has to be capable of mitigating and/or suppressing all types of icing. From that starting point, the typical icephobic coatings must resist to the freezing of the impacting supercooled droplets (repel them or delay their freezing time) [52,58,[80][81][82], lower the freezing temperature of water droplets at continuous solid-liquid contact i.e., sessile droplet mode (freezing temperature depression) [58,77,83] and minimizing or avoiding the frost growth [78,[84][85][86][87]. However, if by some reason icing occurs, another characteristic feature indicating passive icephobicity is the reduced ice adhesion strength compared to plain materials [39,[88][89][90].…”

The severe environmental conditions in winter seasons and/or cold climate regions cause many inconveniences in our routine daily-life, related to blocked road infrastructure, interrupted overhead telecommunication, internet and high-voltage power lines or cancelled flights due to excessive ice and snow accumulation. With the tremendous and nature-inspired development of physical, chemical and engineering sciences in the last few decades, novel strategies for passively combating the atmospheric and condensation icing have been put forward. The primary objective of this review is to reveal comprehensively the major physical mechanisms regulating the ice accretion on solid surfaces and summarize the most important scientific breakthroughs in the field of functional icephobic coatings. Following this framework, the present article introduces the most relevant concepts used to understand the incipiency of ice nuclei at solid surfaces and the pathways of water freezing, considers the criteria that a given material has to meet in order to be labelled as icephobic and clarifies the modus operandi of superhydrophobic (extremely water-repellent) coatings for passive icing protection. Finally, the limitations of existing superhydrophobic/icephobic materials, various possibilities for their unconventional practical applicability in cryobiology and some novel hybrid anti-icing systems are discussed in detail.
