Abstract: The present disclosure relates to a method for preparing a metal catalyst deposited with a layer film by ALD process and a metal catalyst thereof. More specifically, the present disclosure is intended to inhibit sintering of catalyst particles to prevent activity decrease, thus stably maintaining high activity, and simultaneously, providing heat stability, by layer-by-layer deposition of a layer film with alternation of different inorganic films on the surface of a metal catalyst in an ALD process.

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.
