COATED ARTICLE WITH ANTIREFLECTION COATING INCLUDING FULLERENE STRUCTURES, AND/OR METHODS OF MAKING THE SAME
First Claim
1. A method of making a coated article including a broadband anti-reflective coating comprising porous silica on, directly or indirectly, a glass substrate, the method comprising:
- forming a coating solution comprising a silane, fullerene structures comprising at least one functional group, and a solvent;
forming a coating on, directly or indirectly, the glass substrate by disposing the coating solution on the glass substrate;
drying the coating and/or allowing the coating to dry so as to form a coating comprising silica and a fullerene structure-based matrix on the glass substrate;
heat treating the glass substrate with the coating comprising silica and fullerene structure-based matrix thereon so as to combust the fullerene structures, leaving pores following said heat treating in locations where the fullerene structures had been prior to said heat treating, so as to form an anti-reflective coating comprising a porous silica-based matrix on the glass substrate.

Abstract
In certain examples, a porous silica-based matrix may be formed. In an exemplary embodiment, using sol gel methods, a coating solution of or including metal alkoxides such as TEOS and carbon-based structures such as fullerene structures may be used to form a layer(s) of or including silica and fullerene compounds in a solid matrix on (directly or indirectly) a glass substrate. The coated article may be heat treated (e.g., thermally tempered), which may cause the carbon-based fullerene structures to combust, resulting in a porous silica-based matrix. The layer of the porous silica-based matrix may be used as a broadband anti-reflective coating.
