- Abstract
Contact lenses containing high-performance wire grid polarizers (WGPs) were fabricated. The base polymeric membrane was synthesized by copolymerization of 2-hydroxyethyl methacrylate, 3-[tris(trimethylsiloxy)silyl]propyl methacrylate, 1-vinyl-2-pyrrolidinone, methyl methacrylate and ethylene glycol dimethacrylate. The nanopattern was formed by nanoimprint lithography using a UV-curable rubber-toughened epoxy resin on the base membrane. Two consecutive angled aluminium evaporations were performed on the nanopattern, followed by reactive ion etching to form the WGP. The WGP on the membrane was then covered by another layer of the base polymeric material to form the final contact lens. This membrane demonstrated high performance as a polarizer, confirmed by measuring transmittance of transverse magnetic polarized light and transverse electric polarized light. This membrane also demonstrated good performance as a contact lens in terms of modulus, water content and oxygen permeability.
