ANTI-REFLECTIVE COATING AND METHODS OF MAKING THE SAME

摘要

The present invention is directed to anti-reflective coatings and methods of making the same. More specifically, the present invention is directed to porosity graded anti-reflective coatings that are made by methods that comprise preparing a liquid composition with specific amounts of tetraethyl orthosilicate, polyethylene glycol, hydrochloric acid, ethanol, butanol and water; applying the liquid composition onto a surface of a heated substrate; and heating the coated glass system to a temperature higher than that of the heated substrate.
