21. A method of forming an inorganic, stable superhydrophobic surface comprising the following steps:
-
mixing one or more precursors and a solvent to form a first solution; reacting over time a mixed solution to form a reacted solution; applying the reacted solution to a clean substrate; and gelling the reacted solution on the substrate to form the inorganic, stable superhydrophobic surface, wherein the mixed solution is the first solution. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51)
