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. The anti-fingerprint coating can reduce contamination of display devices, appearances of electronic devices or building materials by fingerpris.

What is claimed is: 
     
         1 . A method of forming anti-fingerprint coating, comprising treating a substrate with a composition comprising a lipolytic enzyme. 
     
     
         2 . The method according to  claim 1 , wherein the lipolytic enzyme is a lipase. 
     
     
         3 . The method according to  claim 2 , wherein the composition further includes at least one enzyme selected from the group consisting of a protease, an amylase, a cellulase, and a lactase. 
     
     
         4 . The method according to  claim 1 , wherein the substrate includes plastic or glass. 
     
     
         5 . The method according to  claim 4 , wherein the plastic includes at least one polymer selected from the group consisting of polyester, polypropylene, polyethyleneterephthalate, polyethylenenaphthalate, polycarbonate, triacetylcellulose, olefin copolymers, and polymethylmethacrylate. 
     
     
         6 . The method according to  claim 1 , wherein the lipolytic enzyme is introduced to a surface of the substrate by adsorption, covalent bonds, or encapsulation. 
     
     
         7 . The method according to  claim 6 , wherein the covalent bond is formed through a process including treating the surface of the substrate having at least one functional group selected from the group consisting of amino, amide, carboxyl, aldehyde, hydroxyl and thiol groups with a solution including a bifunctional cross-linker; and dipping the substrate in a buffer including the lipolytic enzyme. 
     
     
         8 . The method according to  claim 6 , wherein the covalent bond is formed through a process including dipping the substrate having an epoxy group at a surface thereof in a buffer including the enzyme. 
     
     
         9 . The method according to  claim 6 , wherein the encapsulation is performed by coating the surface of the substrate with a gel matrix, a microcapsule, a hollow fiber or a membrane, and introducing the lipolytic enzyme. 
     
     
         10 . A substrate comprising anti-fingerprint coating formed by the method according to any one of  claims 1  to  9 . 
     
     
         11 . The substrate according to  claim 10 , wherein the anti-fingerprint coating is formed on a surface of the substrate to have a thickness of about 20 nm to 200 μm. 
     
     
         12 . A product comprising the substrate according to  claim 11 . 
     
     
         13 . The product according to  claim 12 , which is a display device, an electronic device or a building material.
