Anti-Reflective and Anti-Soiling Coatings with Self-Cleaning Properties
The embodiments of the invention are directed to organosilane-based coating compositions having anti-reflective, anti-soiling, and self-cleaning properties; methods of forming of the coatings; and articles of manufacture that utilize the coatings. In some embodiments, the coating compositions comprise an organosilane or mixture of organosilanes, a solvent, optionally an acid catalyst, and optionally a low molecular weight polymer.
1 . A composition, comprising:
an organosilane having a formula of (X) n Si(R) 4-n wherein X comprises halides, alkoxides, carboxylates, phosphates, sulfates, hydroxides, oxides or any combination of thereof; n=1, 2, or 3; and R comprises an alkyl, alkenyl, alkynyl, phenyl, benzenyl hydrocarbon, or fluorocarbon chain comprising 1-20 carbon atoms; and
a solvent.
2 . A composition, comprising:
an organosilane having a formula of (X) n Si—(R) 4-n —Si(X) n wherein X comprises halides, alkoxides, carboxylates, phosphates, sulfates, hydroxides, oxides or any combination of thereof; n=1, 2, or 3; and R comprises an alkyl, alkenyl, alkynyl, phenyl, benzenyl hydrocarbon, or fluorocarbon chain comprising 1-20 carbon atoms; and
a solvent.
