Article Abstract
Ice formation and accretion on surfaces is a serious economic issue in energy supply and transportation. Recent strategies for developing icephobic surfaces are intimately associated with superwettability. Commonly, the superwettability of icephobic materials depends on their surface roughness and chemical composition. This article critically categorizes the possible strategies to mitigate icing problems from daily life. The wettability and classical nucleation theories are used to characterize the icephobic surfaces. Thermodynamically, the advantages/disadvantages of superhydrophobic surfaces are discussed to explain icephobic behavior. The importance of elasticity, slippery liquid-infused porous surfaces (SLIPSs), amphiphilicity, antifreezing protein, organogels, and stimuli-responsive materials has been highlighted to induce icephobic performance. In addition, the design principles and mechanism to fabricate icephobic surfaces with superwettability are explored and summarized.

Ice formation on asphalt roads poses severe safety hazards and maintenance issues, especially in cold climates. Traditional deicing methods are typically energy intensive, environmentally adversive, and economically inadvisable. Alternative superhydrophobic coatings (SHCs) have emerged as promising passive anti-icing solutions.

Ice accumulation on exposed surfaces presents substantial economic and safety challenges across various industries. To overcome limitations associated with traditional anti-icing methods, such as the use of nanoparticles, this study introduces a novel and facile approach for fabricating superhydrophobic and anti-icing microstructures using cost-effective LCD 3D printing technology. The influence of diverse pillar geometries, including square, cylindrical, hexagonal, and truncated conical forms, was analyzed to assess their effects on the hydrophobic and anti-icing/icephobic performance in terms of wettability, ice adhesion strength, and icing delay time.

Subcooled superhydrophobic surfaces have notable applications in aerospace, energy, and refrigeration industries. Superhydrophobic behavior can be achieved with different microscale surface morphologies which can impact the water repellency and icephobicity of the surface. To comprehensively study how surface microstructure influences the spreading, rebounding, and freezing behavior of impacting droplets at various surface temperatures and droplet velocities, several types of surfaces were prepared within this study.

We report a rapid and scalable method for fabricating hierarchically microstructured polyether ether ketone (PEEK) surfaces using high-speed femtosecond laser treatment. The resulting structures exhibit two primary morphological features: cylindrical hills (11-16 μm in diameter) formed by ablation and a micro-/submicron-scale mesh originating from melt flow and resolidification. These features significantly modify surface wettability, increasing the water contact angle (WCA) up to 136° and promoting complete wetting by hexadecane.
