DUST REPELLENT SILICA AND TITANIA COATINGS
Novel coatings disclosed herein can be used to mitigate dust adhesion. In one embodiment, a method of making a dust repellant coating includes combining a titanium dioxide sol with colloidal silica to form a mixture. The method also includes adding solvent to the mixture, stirring the mixture for about an hour, and filtering the mixture into a solution of titanium dioxide and silica dioxide.
1 . A dust repellant coating, comprising:
about one part of a titanium dioxide sol;
about nine parts of colloidal silica combined with said titanium dioxide sol; and
about ten parts of solvent stirred with said titanium dioxide and said colloidal silica for about an hour, and filtered into a solution of titanium dioxide and silica dioxide.
2 . The dust repellant coating of claim 1 , wherein:
the dust repellant coating is operable for application to a surface via at least one of a chemical vapor deposition, a pulsed laser deposition, a physical vapor deposition, an electrochemical deposition, a spray coating, a roll-to-roll coating, a spin-coating, or a dip-coating.
3 . The dust repellant coating of claim 1 , wherein:
the dust repellant coating is operable to repel dust in a vacuum.
4 . The dust repellant coating of claim 1 , wherein:
the dust repellant coating is operable to repel dust in air.
5 . The dust repellant coating of claim 1 , wherein:
the dust repellant coating is operable for application to a surface in a vacuum.
6 . The dust repellant coating of claim 1 , further comprising:
at least one of a metal additive, an organic additive, a metal salt, or a metal oxide.
7 . The dust repellant coating of claim 6 , wherein:
the metal oxide comprises at least one of alpha alumina, gamma alumina, titania, zirconia, copper oxide, zinc oxide, or mixtures thereof.
8 . The dust repellant coating of claim 6 , wherein:
the metal salt comprises at least one of copper, silver, chromium, aluminum, gold, or mixtures thereof.
10 . The dust repellant coating of claim 6 , wherein:
the organic additive comprises at least one of methanol, ethyl alcohol, isopropyl alcohol, 1-butanol, 2-butanol, isobutanol, tert-butanol, or mixtures thereof.
11 . The dust repellant coating of claim 1 , wherein:
the solvent comprises isopropanol.
