“…Another popular way is to combine the active and passive methods 193–195 . Based on the nonadhesive performance of the superhydrophobic, or slippery, surface, the ice prevention and removal properties can be significantly improved by coupling with the electro‐, or photo‐, thermal effect 196–198 (Figures 9d and e, respectively).…”

“…Another popular way is to combine the active and passive methods. [193][194][195] Based on the nonadhesive performance of the superhydrophobic, or slippery, surface, the ice prevention and removal properties can be significantly improved by coupling with the electro-, or photo-, thermal effect [196][197][198] (Figures 9d and e, respectively). The electrothermal strategy is a simple way to fabricate two layers that consist of a functional layer and an electrothermal layer, respectively.…”

“…220 Inspired by this rapid cascadefolding mechanism, the superhydrophobic substrates show excellent water/ice repellency performances with macrodeformation abilities (Figure 10b). For example, Kamran et al 195 developed a passive deicing system with a low ice adhesion strength, which could remove the ice by pressing air into the channels, or by melting the ice by heating the air in the channels. As can be seen in Figure 10d, the ice bulk was bounced off from the surface under a pressure of 21 kPa.…”

Unwanted ice formations may cause severe functional degradations of facilities and also have a negative impact on their lifespans. Avoiding and removing ice accumulation is always a hot topic in the industrial and technological field. Bionic functional surfaces have been greatly studied for several decades and have proved to be excellent candidates for passive anti‐/deicing applications. However, the drawbacks limit their potential industrial uses under harsh conditions, like low temperatures and high humidity. Most researches on bionic surfaces are focused on a certain function of natural creatures and their underlined fundamental theories are revealed by taking the interface as the static. Actually, living organisms, either plants or animals, are often sensitive and responsive to their surroundings, avoiding risks and even self‐repairing upon damage. From this prospect, a novel view of the bionic icephobic materials has been proposed in the present review, which is expected to be studied and designed by taking the biological species as a system. As two representative icephobic materials, the anti‐/deicing theories of superhydrophobic and slippery surfaces are first discussed. Further, the recent progress of smart icephobic strategies is summarized from interfaces to substrates. We aim to provide new bionic insights on designing future icephobic strategies.

“…While at first perhaps counterintuitive, compliant metal sheets have recently demonstrated excellent de-icing performance that has been attributed to a plate buckling instability. [8,9,11] STFs are a class of non-Newtonian fluids that can rapidly increase in viscosity when sheared, and exhibit a solid-like response to impacts beyond a critical shear rate. [12][13][14] STFs have been successfully integrated into sandwich composite panels to enhance structural impact resistance.…”

Ice buildup can significantly and negatively impact system performance in various industrial sectors, and has remained a persistent challenge for decades. Many compliant materials exhibit excellent de‐icing performance but are easily eroded by impacts from supercooled water droplets, sand, dust, and debris. A composite panel inspired by animal skin, consisting of a facesheet protecting a nanofluid layer beneath, which exhibits durable anti‐icing and tunable photothermal properties is proposed. The viscous liquid layer beneath the facesheet increases flexural rigidity, preventing large deflections and increasing deformation resistance, which alters ice's adhesion to the surface. The non‐uniform fluid pressure exerted by the viscous nanofluid‐filled composite panels facilitates ice detachment, resulting in ice adhesion strengths as low as τice ≈ 10 kPa. Further, by altering the fluid properties, different additional functionalities can be endowed to the system. Incorporating fumed silica in a fluid‐filled composite panel results in rheopectic behavior, and this doubles their impact resistance when the shear thickening properties are properly tuned. Additionally, the combination of a transparent facesheet and a solar light absorbent nanofluid allows for tunable photothermal properties, further enhancing the anti‐icing performance of the system. This durable and tunable nanofluid‐filled composite panel shows great promise as a multifunctional de‐icing material.

To tackle the formidable challenges posed by extreme cold weather events, significant advancements have been made in developing functional surfaces capable of efficiently removing accreted ice. Nevertheless, many of these surfaces still require external energy input, such as electrical power, which raises concerns regarding their alignment with global sustainability goals. Over the past decade, increasing attention has been directed toward photothermal surface designs that harness solar energy−a resource available on Earth in quantities exceeding the total reserves of coal and oil combined. By converting solar energy into heat, these designs enable the transformation of the interfacial solid‐solid contact (ice‐substrate) into a liquid‐solid contact (water‐substrate), significantly reducing interfacial adhesion and facilitating rapid ice removal. This critical perspective begins by emphasizing the advantages of photothermal design over traditional de‐icing methods. It then delves into an in‐depth analysis of three primary photothermal mechanisms, examining how these principles have expanded the scope of de‐icing technologies and contributed to advancements in photothermal surface design. Finally, key fundamental and technical challenges are identified, offering strategic guidelines for future research aimed at enabling practical, real‐world applications.
