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.
