Adaptable, Dynamic, and Superhydrophobic Standing‐Fiber Surface with Muti‐Level Energy Barrier for Anti‐Icing

Abstract Passive deicing technologies achieved by dynamic superhydrophobic surfaces and slippery substances contribute to widely used anti‐icing. However, the constant status of microstructures cannot cater to the changing environment, meanwhile, the energy barrier needs to be improved. Here, a dynamic superhydrophobic standing‐fiber surface with a three‐level energy barrier is fabricated by electrical flocking technology, which directly utilizes the wind field to assist anti‐icing. The standing‐fiber surface has low ice adhesion of 2.7 kPa, a high water contact angle of 171.1°, and a long icing delay time of 859 s under −30 °C. The superhydrophobicity contributes to excellent water repellency with a droplet retracting and bouncing distance of 3.53 and 3.75 mm. In the wind field at 9 ms ⁻¹ , the inclined standing‐fiber surface theoretically accelerates the motion of the water droplet by 1.5 times compared with the lying‐fiber surface. The difference in thermal conductivity between the front and back sides of the standing‐fiber surface makes it an ideal candidate for designing anti‐icing, deicing, and thermal insulation clothes.
