Abstract
A water-repellent textile is produce by applying to a textile a solution of Al13 nanoclusters or aluminum nitrate or hydrates of aluminum nitrate in a solvent to produce a wetted textile; and photo-annealing the wetted textile with ultraviolet light having a wavelength in the range of 180 nm to 260 nm to produce an Al2O3 coating on fibers of the textile. The textile may be, for example, cotton, polyester, wool, nylon, chiffon, nubuck, leather, burlap, silk, denim, or any combination thereof. Preferably, the solvent is a solubilizing organic solvent, pure water, or a miscible organic/water solvent mixture.
Claims12
A method for producing a water-repellent textile, the method consisting of:
- applying to a textile a solution of Al13 nanoclusters in a solvent to produce a wetted textile;
- wherein the solution is a solution of Al13 nanoclusters in acetone/water, where the Al13 nanoclusters are flat-Al13 nanoscale clusters, Al13(μ3-OH)6(μ-OH)18(H2O)24(NO3)15;
- and
- photo-annealing the wetted textile with ultraviolet light having a wavelength in the range of 180 nm to 260 nm at ambient temperature to produce an Al2O3 coating on fibers of the textile to produce the water-repellent textile.
