Abstract

Coating solutions having anti-reflective and anti-static properties, a coating derived therefrom, a substrate coated with the coating and methods for their preparation. A coating includes a sol-gel alkoxide polymeric material and a conductive colloidal metal compound material.

Claims

1. A method for preparing a coating solution comprising:

subjecting a solution of an alkoxide to hydrolyzation and condensation in a reaction system;

aging the solution to form a sol-gel reaction product; and

diluting the reaction product.

2. The method of claim 1, wherein the alkoxide comprises one of the general formula:

M(OR)_x

wherein M is selected from at least one of the group consisting of Si, Ti, B, Al, and Zr,

wherein R is an alkyl group having 1-8 carbons and x is the valence state of the cation.

3. The method of claim 1, wherein the aging comprises 1 to 24 hours at 50°
