PROCESS FOR MANUFACTURING ARTICLES WITH GRADED NANOVOIDS
The present invention relates to a process for producing a gradient low refractive index coating, comprising coating a dispersion on a surface of a substrate, the dispersion comprising an ultraviolet (UV) radiation curable material, a photoinitiator; a solvent; and a plurality of nanoparticles, providing at least a 100 part per million (ppm) oxygen atmosphere adjacent the dispersion, irradiating the dispersion with UV radiation to at least partially polymerize the UV radiation curable material, forming an insoluble polymer matrix binding the plurality of nanoparticles, and including a plurality of nanovoids, the plurality of nanovoids being filled with the dispersion depleted of the polymerizable material and the nanoparticles, wherein a first volume fraction of the plurality of nanovoids proximate the surface of the substrate is greater than a second volume fraction of the plurality of nanovoids proximate an opposing surface of the insoluble polymer matrix; and removing a major portion of the solvent from the dispersion after at least partially polymerizing the polymerizable material..
