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.
Claims7
A polymer film which is coated with a sulfur-containing copolymer, wherein the polymer film has a refractive index of 1.7 to 1.9, a transmittance of 90 to 99.9% in a visible spectrum, a sulfur content of 60 to 80 wt %, and a sulfur rank of 2.0 to 8.0, and the sulfur-containing copolymer is selected from the group consisting of poly (sulfur-co-1,9-decadiene) (SDDE) and poly (sulfur-co-1,11-dodecadiene) (SDDDE).
