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.

A method of growing carbon nanotubes includes following steps. A reactor is constructed, wherein the reactor includes a reactor chamber and a rotating mechanism inside the reactor chamber. A carbon nanotube catalyst composite layer is applied, the carbon nanotube catalyst composite layer is configured to be rotated by the rotating mechanism in the reactor chamber, and the carbon nanotube catalyst composite layer includes a carbon nanotube layer and a number of catalyst particles dispersed in the carbon nanotube layer.
