The invention relates to a method for preparing a vinyl ether polymer by photo-initiated polymerization, which comprises the step of: under a protective atmosphere, performing photo-initiated polymerization on a vinyl ether monomer in the presence of an organic halogenated hydrocarbon and manganese carbonyl under irradiation of light having a wavelength of 365-550 nm at −25° C. to 25° C., to obtain a vinyl ether polymer after the reaction is completed. In the method, a vinyl ether monomer is subjected to cationic polymerization in the presence of manganese carbonyl and an organic halogenated hydrocarbon under visible light, to prepare a vinyl ether polymer with controlled molecular weight and narrow molecular weight distribution.

The present invention relates to a technology of solving an issue where screens are contaminated with pollution caused by fingerprints, cosmetics, etc. on covers or windows of mobile devices such as smartphones, tablets, etc. and other user contact devices, thereby maintaining the excellent surface hardness properties of existing covers or windows and preventing deterioration of surface properties (antifouling properties) even when used long-term. The method for forming a surface having super water-repellent and super oil-repellent properties comprises the steps of: etching a surface of a target on which a surface with super water-repellent and super oil-repellent properties will be formed, to thereby form a surface structure in which convex parts () and concave parts () are continuously formed; and performing a conformal coating for coating a fluorine-based material on the surface structure which is etched on the surface of the target, wherein all configuration walls of the convex parts and all configuration walls of the concave parts are coated at a uniform thickness.
