Abstract
A polymer or polymer composite membrane having through-thickness micropores and a method of preparing the same are provided. More particularly, a polymer or polymer composite membrane having a pore structure such that micropores are aligned in a mesh structure in the thickness direction of the polymer or polymer composite membrane due to unidirectional freezing in the thickness direction of a solvent. The membrane has through-thickness micropores, and thus has improved permeability in the thickness direction and superior uniformity in size of the micropores and wall thickness between the micropores. For these reasons, the membrane can be used for a porous membrane substrate, microfiltration membrane, etc.
