Abstract

Superhydrophobic materials have become a feasible choice to solve related difficult problems because of their excellent anti-icing, anti-corrosion, and self-cleaning characteristics. In this work, a superhydrophobic hydroxypropyl methylcellulose (HPMC)/SiO₂ coating is prepared using an efficient, fluorine-free method for the anti-icing application of transmission line insulators and other similar material surfaces. The water contact angle (WCA) of the coating is 161°, and the slide angle (SA) is less than 1°. The coating maintains good hydrophobicity after mechanical durability tests. In the anti-icing performance tests, the start freezing time of a single droplet is delayed by 1366 s, and when the surface is not coated, the ice amount is more than twice that with the coating. Therefore, this work provides a straightforward and promising solution to solving high-cost and low-efficiency difficulties in the anti-icing problem of transmission line insulators and other similar material surfaces.
