Abstract:
A composition includes: a continuous liquid phase including an acrylic monomer and an epoxy monomer; and a dispersed nanoparticulate including ZrO2 modified with an acrylic silane; and wherein the composition is transparent to visible light when coated on a lens. In addition, a method including the steps of: mixing an acrylic silane and a methanol-based ZrO2 sol to create a methanol-based silane-modified ZrO2 sol; then mixing at least an acrylic monomer, an epoxy monomer, and the methanol-based silane-modified ZrO2 sol to obtain the composition. The composition can be adapted for coating and curing onto another substrate, such as an ophthalmic lens.
