RESIN FILM AND METHOD FOR MANUFACTURING RESIN FILM

摘要

Disclosed herein is a resin film. The resin film has a height difference of about 10 nm to about 65 nm between a convex portion and a concave portion on an outermost surface thereof, and has a difference in contact angle (ΔCA) of less than about 10°, as represented by Equation 1:;ΔCA=|CA2−CA1|  [Equation 1];Where in Equation 1, CA1 is a water droplet contact angle after a surface of a substrate coated with the resin film has been subjected to a 500-cycle reciprocating abrasion test using an eraser under a load of 500 g/cm2, and CA2 is a water droplet contact angle before the reciprocating abrasion test.;Embodiments of the invention provide a novel and improved resin film capable of improving antifouling and slip properties and enhancing film strength, and a method of manufacturing the same.
