Claim Text:
1. A process for producing a nanovoided article, comprising: providing a first solution comprising a polymerizable material in a solvent, wherein the first solution further comprises nanoparticles, and wherein a weight ratio of polymerizable material to the nanoparticles in the first solution is greater than about 30:70; at least partially polymerizing the polymerizable material with ultraviolet (UV) radiation produced by at least one light emitting diode (LED) to form a composition comprising an insoluble polymer matrix substantially bicontinuous with a second solution, wherein the insoluble polymer matrix comprises a plurality of nanovoids that are filled with the second solution, and wherein at least some of the nanoparticles are bound to the insoluble polymer matrix during the polymerizing step; and removing a major portion of the solvent from the second solution.
