Abstract:
Anti-reflection (AR) coating for a glass substrate is prepared by blending at least two different sols to form a coating sol which is used to coat a substrate such as a transparent glass substrate. In certain example embodiments, a method includes forming a first sol formulation including a colloidal solution having a tri-alkoxysilane based binder; forming a second sol formulation including a colloidal solution having a tetra-alkoxysilane based binder; blending the first and second sol formulations to form a coating sol formulation; coating at least a portion of said coating sol formulation onto the glass substrate to form a coating; and heating (e.g., for curing and/or annealing) the glass substrate and the coating thereon. Anti-reflection glasses show improved mechanical strength and higher transmittances (e.g., Tqe % gain).

Abstract:
A method of making a coated article including an anti-reflection coating on a glass substrate, the method comprising: mixing at least a tri-alkoxysilane based binder and a tetra-alkoxysilane based binder with at least silica based nanoparticles and a solvent in forming a coating sol formulation; aging the coating sol formulation at least about two weeks so as to provide an aged coating sol formulation; coating at least a portion of said aged coating sol formulation onto the glass substrate to form a coating; and heating said glass substrate and said coating. Anti-reflection (AR) glasses show improved mechanical strength and higher transmittances (e.g., Tqe % gain).
