PROBLEM TO BE SOLVED: To provide a process and apparatus for producing a nanovoided article, a nanovoided coating, and a low refractive index coating.SOLUTION: The process includes the steps of: providing a first solution of a polymerizable material in a solvent; at least partially polymerizing the polymerizable material to form a composition that includes an insoluble polymer matrix and a second solution, where the insoluble polymer matrix includes a plurality of nanovoids that are filled with the second solution; and removing a major portion of the solvent from the second solution. An apparatus for the process is also described, and includes a webline, a coating section, a partial polymerization section, and a solvent removal section. |
