“…However, it is worth mentioning that, for the cases when the temperature is above 11 • C, the soft layer may have adverse effects on the ice adhesion strength; this can be explained from the reactive bubbles that create a thermal insulation layer that actually keep the ice from the heat generated from the thermal activation resistor, as previously seen in Figure 10. A comparison of the adhesion-breaking strength with other published methods, such as surfaces modified with SiC carbon nanotubes [22], oil-impregnated polyurethane [23], UV-modified PDMS [24], and novel porous photothermal material [8], has also been made, as seen in Figure 12b. The proposed soft layers exhibit low adhesion strength in this category.…”

“…Measured interface-breaking strength. Note: the error bars in (a) indicate combined sensor uncertainty, which is calculated based on RSS uncertainty, taking all of the input and sensors into account, assuming the tip is 90% in contact with the ice, and the results in (b) compare the adhesion breaking strength values among the reported work (SiC-CNT[22], OIP[23], UV PDMS[24], and porous photothermal material[8]) and the one in this work.…”

The prompt removal of ice is crucial to the safe operation of maritime equipment. However, traditional deicing approaches such as steam jets or manual tools are costly in terms of energy consumption and human labor. If the ice interfacial strength can be reduced, the above problems can be much alleviated. Therefore, this paper introduces a new type of low-cost, thermally activated sacrificial soft layer that can change phase according to the user’s activation signal to reduce the surface–ice adhesion strength. The proposed gelatine soft layers, containing an environmentally friendly compound (CH3COOH or NaHCO3), are prepared in 50–70 mm2 films with a thickness between 0.5 mm and 0.8 mm at room temperature in around 1 h. Layers containing different chemical compounds are stacked vertically, which stay inert at room temperature or lower, but can be thermally activated to change from a solid to gas–liquid phase. The CO2 gas released from the chemical reaction is trapped between the surface–ice interface, greatly reducing the overall contact area, as well as the surface–ice adhesion strength. An experimental testbed was assembled in the lab, capable of measuring the interfacial ice adhesion strength according to the deflection of a polyurethane cantilever beam. The initial test results showed the promising properties of the layers, where no expansive equipment is required during the sample preparation, and the cost of raw materials to make a pair of soft layers is well below 0.1 USD/mm2. Under a −13 °C environment, the surface–ice adhesion strength of pure water ice was found to reduce by over 20%.

“…Surficial ice on the equipment can cause serious damage or increase maintenance costs, so many strategies have been developed to inhibit the ice growth or remove the ice on the equipment surface. , Given the outstanding interfacial photothermal property and high hydrophobicity of SFMMM, the photothermal de-icing performance was carried out (Figure A). The cotton membrane exhibits a superior hydrophilicity with complete infiltration in 0.1 s, while the SFMMM keeps remarkable hydrophobicity with a WCA of 125° even after 10 min (Figure B).…”

The microstructure of photothermal interface materials for solar steam generation is crucial to simultaneously optimize the water transfer path and solar-to-vapor conversion efficiency; however, it remains a formidable challenge. Herein, bioinspired by the spindle knot structure of spider silk, spindleknotted nanofibrous mixed-matrix membranes are facilely prepared and exhibit highly efficient solar-to-vapor conversion due to the "spindle knot effect" that results from the localized solar-to-thermal conversion at the spindle knots and water's directional movement on the spindle knots' surface. The asprepared membrane achieves an evaporation rate of 2.41 kg m −2 h −1 with a conversion efficiency of 95.9% under 1 Sun and a maximum water production of 4.81 kg m −2 in 1 day. Besides, it can output a high electric power of 0.89 W m −2 to power small devices due to the Seebeck effect and exhibit strong ice removal performance. This work reports the bioinspired strategy for constructing multifunctional photothermal interface materials.

Water is the source of life and civilization, but water icing causes catastrophic damage to human life and diverse industrial processes. Currently, superhydrophobic surfaces (inspired by the lotus effect) aided anti‐icing attracts intensive attention due to their energy‐free property. Here, recent advances in anti‐icing by design and functionalization of superhydrophobic surfaces are reviewed. The mechanisms and advantages of conventional, macrostructured, and photothermal superhydrophobic surfaces are introduced in turn. Conventional superhydrophobic surfaces, as well as macrostructured ones, easily lose the icephobic property under extreme conditions, while photothermal superhydrophobic surfaces strongly rely on solar illumination. To address the above issues, a potentially smart strategy is found by developing macrostructured photothermal storage superhydrophobic (MPSS) surfaces, which integrate the functions of macrostructured superhydrophobic materials, photothermal materials, and phase change materials (PCMs), and are expected to achieve all‐day anti‐icing in various fields. Finally, the latest achievements in developing MPSS surfaces, showcasing their immense potential, are highlighted. Besides, the perspectives on the future development of MPSS surfaces are provided and the problems that need to be solved in their practical applications are proposed.
