Abstract
An article comprising substrate having a surface and a coating on the surface of the substrate, the coating comprising a fluoropolymer and a fluorochemical surfactant. The fluoropolymer and the fluorochemical surfactant are selected such that the article is anti-reflective, abrasion resistant and anti-fogging. Methods of making the same are also described.

An article comprising an optically transparent substrate having a surface and a coating on the surface of the substrate, said coating comprising a fluoropolymer and a fluorochemical surfactant, said fluoropolymer and fluorochemical surfactant being selected such that the coated article is anti-reflective, abrasion resistant and anti-fogging.
A method of imparting anti-reflective, abrasion resistance, and anti-fogging properties to an optically clear substrate, the method comprising the steps of:
- providing a substrate having a surface;
- providing a coating composition on the surface of the substrate, the coating composition comprising a fluoropolymer and a fluorochemical surfactant;
- and
- causing the coating composition to harden on the surface of the substrate;
- said fluoropolymer and fluorochemical surfactant being selected such that the substrate coated with the coating composition is anti-reflective, abrasion resistant, and anti-fogging.
