Abstract
Embodiments of the present disclosure relates generally to methods of providing biomimetic superhydrophobic coatings to substrates, and more specifically to providing biomimetic inorganic silica or silane-based coatings that enable tunable hierarchical surface structures with high coating-to-substrate adhesion, resistance to various mechanical abradents, durability, shelf stability, and enhanced non-wettability or water-repellency.
Claims42
A coating process comprising:
- mixing an inorganic silica- or silane-based coating comprising an inorganic silica or silane, a catalyst, and a dispersion medium in a ratio of from about 1:2:22 to about 1:30:25 for a reaction time;
- soaking a substrate in the mixture for a soaking time;
- and
- drying the soaked substrate.

A coating process comprising:
- mixing a non-fluorinated inorganic silica- or silane-based coating comprising a non-fluorinated inorganic silica or silane, a catalyst, and a dispersion medium in a ratio of from about 1:2:22 to about 1:30:25 for a reaction time;
- coating a fabric substrate with the mixture;
- drying the coated substrate;
- and
- annealing or curing the dried substrate;
- wherein the reaction time is sufficient to enable hydrolysis and condensation of the inorganic silica or silane.
