Abstract
Provided herein are a sulfur copolymer derived from an elemental sulfur and a thiol monomer and a method for preparing the same. The sulfur copolymer is synthesized by a simple method, and can be widely used in cameras and lenses, or defense materials-related industries, by replacing expensive inorganic materials used in existing infrared lenses. In addition, by adjusting the content of one or more sulfur monomers or two or more sulfur monomers, not only mid-wave infrared transmission but also long-wave infrared transmittance can be maintained at a high level.
Claims14
A sulfur copolymer comprising a repeating unit comprising benzene and one or more sulfur monomers,
- wherein the repeating unit is represented by Chemical Formula 2:
- wherein n1 to n3 are integers from 0 to 100, and are the same as or different from each other.
