Abstract: Provided are a porous structure for forming anti-fingerprint coating capable of providing a self-cleaning function to a surface of a substrate, a method of forming anti-fingerprint coating using the same, an anti-fingerprint coated substrate prepared by the same method, and a product including the same. When the porous structure including a lipolytic enzyme is formed on the surface of the substrate, contaminants decomposed by an enzyme are absorbed into a pore, and thus anti-fingerprint coating may be more effectively performed to remove detectable contamination from a surface of the substrate. As a result, contamination by fingerprints on the surface of a display device, the appearance of an electronic device, or building materials can be effectively reduced.

Abstract: Provided are a novel use of a lipolytic enzyme for forming anti-fingerprint coating, a method of forming anti-fingerprint coating including treating a substrate with a composition comprising the lipolytic enzyme, a substrate including the anti-fingerprint coating formed by the same method, and a product including the same.
