Abstract

The present invention relates to a method of preparing a polymer film using chemical vapor deposition using sulfur as an initiator (sCVD) capable of manufacturing a polymer film through polymerization of sulfur and a monomer using gas-phase sulfur as an initiator. In the manufactured polymer film, any of various monomers and sulfur can be polymerized into a copolymer, and it is possible to manufacture a polymer film having a high content of sulfur, an excellent refractive index, and excellent transmittance.
