Recently, a self-cleaning jet waterproof film was developed by Bassfire.

The film forms a nanostructured surface that mimics the surface of a lotus leaf when dried, and wax nanocrystals with a diameter of approximately 1 nm: arranged in the form of peaks and valleys, the water on the surface turns into water droplets and rolls off, under a rainstorm surface It can also be kept dry while the water droplets collect fine dust particles during rolling so as to achieve a surface "self-cleaning" effect. This film based on polypropylene, polyethylene and wax nanoparticles can be used to make self-cleaning windows. It can also be used in paper, leather, textile and masonry construction. The film can be sprayed onto the surface of the object using a commonly used aerosol, and when it gradually disappears, it can be easily re-applied once.
