POLYMER MEMBRANE FOR GAS SEPARATION OR ENRICHMENT COMPRISING HYBRID NANOPOROUS MATERIAL, USES THEREOF, AND A PREPARATION METHOD THEREOF

摘要

Disclosed herein is polymer membrane for gas separation or concentration which contains a hybrid nanoporous material, an application thereof, and a manufacturing method thereof.;Especially, the hybrid nanoporous material has a window size of 4 Å to 15 Å or has gas adsorption characteristics for a gas to be separated, which is different from those for other gases, and thus the present invention may provide the polymer membrane having improved gas permeation selectivity, an application thereof, and a manufacturing method thereof.

主权项

1. A polymer membrane for separating or concentrating a first gas or a second gas from a gas mixture including the first gas having a first monomolecular size V1 and the second gas having a second monomolecular size V2 (V1≠V2), the polymer membrane comprising:
a polymer matrix; and particles of hybrid nanoporous material dispersed in the polymer matrix, wherein the polymer matrix in the polymer membrane permeates the first gas and the second gas at different rates, and the hybrid nanoporous material has window size or adsorption characteristics for permeating the first gas, not the second gas.
