Title COMPOSITE MEMBRANE AND METHOD OF SEPARATING GAS USING THE SAME
Abstract Disclosed is a composite membrane comprising a mixed matrix membrane comprising a polymer matrix and fillers dispersed in the polymer matrix. The polymer matrix comprises a polymer having a polar functional group. The H2 permeability coefficient of the polymer matrix is 20 Barrer or more at 4 bar and 298 K. The filler has a polar functional group that may be capable of forming a hydrogen bond with the polar functional group of the polymer, and has an average diameter of 100 nm or less.
Outline of related art and contending technology BACKGROUND ART
Study has recently been undertaken with respect to Mixed Matrix Membranes (MMMs) for gas separation in which metal organic frameworks (MOFs) are added to polymer matrix (see Non-patent Literatures 1 and 2).
