Title:
SUBSTRATE HAVING AT LEAST ONE PARTIALLY OR ENTIRELY FLAT SURFACE, AND USE THEREOF
Document Type and Number:
WIPO Patent Application WO/2013/187541
Kind Code:
A1
Abstract:
The present invention provides a substrate, at least one surface of which is partially or entirely flat, wherein the substrate is characterized by comprising: a substrate molded from first substrate-forming particles; second substrate-forming particles partially or entirely filled into first pores which are formed by the first substrate-forming particles on at least one surface of said substrate; and a polymer partially or entirely filled into second pores remaining in a region in which the second substrate-forming particles are filled. In addition, the present invention provides a method for preparing a thin film or a thick film, comprising the steps of: aligning non-spherical seed crystals on a flat portion of at least one surface of the substrate according to the present invention such that an a-axis, a b-axis, and/or a c-axis are oriented according to a certain rule; and exposing the aligned seed crystals to a solution for enabling the growth of the seed crystals to thereby form and grow a film from the seed crystals using a secondary growing technique. The film formed using the substrate according to the present invention can be used as a high-performance molecular separation membrane.
