Title:
POLYMER OR POLYMER COMPOSITE MEMBRANE HAVING THROUGH-THICKNESS MICROPORES, AND METHOD FOR PREPARING SAME
Document Type and Number:
WIPO Patent Application WO/2011/149165
Kind Code:
A1
Abstract:
The present invention relates to a polymer or polymer composite membrane having through-thickness micropores, and a method for preparing same, and more particularly, a polymer or polymer composite membrane having a pore structure such that micropores are arranged in the form of a mesh, in the thickness direction of the polymer or polymer composite membrane due to unidirectional freezing in the thickness direction of a solvent. The present invention has through-thickness micropores, thus has improved penetratability in the thickness direction and superior uniformity in the size of the micropores and in the thickness of the walls therebetween, and thus can be used for a porous membrane substrate, microfiltration membrane, and the like.
