Document Type and Number:
WIPO Patent Application WO/2019/208888
Kind Code:
A1
Abstract:
A manufacturing method for a polymeric film according to an embodiment of the present invention comprises the steps of: (a) forming a microstructured pattern, which has a nanostructured pattern formed on a surface thereof, on one surface of a metal substrate to be used as a mold; (b) forming a superhydrophobic coating layer on the pattern of the metal substrate; (c) applying a liquid polymeric layer on one surface of the metal substrate, on which the coating layer has been formed, followed by curing; and (d) immersing, in an ethanol solution, the metal substrate having the cured polymeric layer formed on one surface thereof, and then separating the cured polymeric layer from one surface of the metal substrate.
