Abstract

See full text

Sulfur copolymers and methods of synthesizing said sulfur copolymers are described herein. Sulfur monomers copolymerize with epoxide or vinylic moieties the epoxy-functionalized styrenic comonomers to form a crosslinked network of the sulfur copolymer. Sulfur copolymers having high sulfur content are used as raw materials in 3D printing. Chalcogenide-based copolymers can utilize selenium to provide for the optical properties. Using an inverse vulcanization method, chalcogenic sulfur copolymers are used to prepare chemically stable polymer plastic materials with tunable optical and thermochemical properties. Optical substrates, such as films, waveguides, and molded (nano-, micro-) objects and lenses, are constructed from sulfur copolymers via 3D printing and are substantially transparent in the visible and infrared spectrum.
