Preparation and anti-icing performance of fluorosilicate superhydrophobic anti-icing coating

Abstract In response to the issues of complex and cumbersome preparation and coating processes for various superhydrophobic materials, as well as insufficient superhydrophobic and anti-icing performance, we have developed a superhydrophobic anti-icing coating based on fluorosilicone rubber. By using hydroxyl silicone oil and silicone oil as base materials, and incorporating nano powders, fillers, and modified additives, we have developed a fluorosilicone superhydrophobic anti-icing coating that cures at room temperature. The performance of this coating has been characterized, and the results show that it has good storage stability, with a contact angle of up to 150° and a rolling angle of less than 10°. In terms of anti-icing performance, the ice adhesion strength on the coated surface is only 40-80 kPa. Regarding durability, the coating still possesses good superhydrophobic capabilities and anti-icing performance after being subjected to a period of wet and cold environment spraying. In simulated icing tests, the delay in ice formation on the coated wire surface can reach 30-40 minutes. This coating is an excellent choice for anti-icing coatings.
