Abstract
Poly(dimethylsiloxane) is a common dispersant, modifier, and binder in the field of bioinspired wettability. Herein, the soot production when poly(dimethylsiloxane) was burning was used to directly construct a superhydrophobic coating with the water contact angle reaching 159.7°. After the lubricant was infused, its transparency was greater than 80% of air in the visible light range of the human eye. In addition, the sliding angle and contact angle of the coating were stable for 15 days. It showed excellent oil-locking ability and stability. Even if the superhydrophobic coating was immersed in various organic solvents for 15 days, its hydrophobicity did not change. Moreover, the coating had an excellent anti-fouling ability and self-cleaning ability to meet actual application conditions. Furthermore, the preparation method was simple and rapid, without the participation of fluorine-containing modifiers, and provides a brand-new method for preparing transparent lubricant-infused surfaces.
