Flexible fabric having superhydrophobic surface

摘要

The disclosure relates to a superhydrophobic surface. Methods of fabrication are disclosed including laminating an optically transparent polymer sheet with hydrophobic nanoparticles such that the nanoparticles are partially embedded and partially exposed. The resulting assembly remains optically transparent. Additional methods include the lamination of nanoparticles to flexible fabrics and the production of molded articles using nanoparticle-treated molds.

主权项

1. A flexible article comprising:
a flexible fabric comprising a first side and a second side, opposite the first side; a polymer laminated to the first side of the flexible fabric, the polymer comprising a first surface and a second surface, wherein the first side of the flexible fabric is contiguous with the second surface of the polymer; and a plurality of nanoparticles partially embedded and partially exposed on the first surface, wherein the polymer has extruded between agglomerates formed by the nanoparticles to provide a plurality of polymer filaments ranging in length from about 1 microns to about 100 microns and in diameter from 20 nm to 500 nm, to provide a superhydrophobic surface, the nanoparticles having an average diameter of less than 100 nm.
