| titleOfInvention | High permeability polymer composite membrane for gas separation and method of making the same |
| abstract | The invention provides a high-permeability polymer composite membrane for gas separation, which is formed by compounding azo-bridged inherent microporous polymer and polyarylethersulfone ketone. The preparation method of the composite membrane is also provided, and comprises the steps of dissolving the azo-linked inherent microporous polymer in an organic solvent, and then adding polyarylethersulfone ketone for stirring to obtain a polymer solution; and then filtering and removing impurities from the polymer solution, pouring the polymer solution into a mold, and drying, removing residual organic matters, air-drying and drying to obtain the polymer. The novel azo-linked inherent microporous polymer is synthesized, the polyarylethersulfone ketone is doped into the novel azo-linked inherent microporous polymer, the compatibility of the polymer and a high polymer material is improved, a certain channel can be provided for gas molecules by a unique pore channel of the polymer in the obtained composite membrane, the gas permeability of oxygen, nitrogen and carbon dioxide is improved to a great extent, and the gas separation performance is obviously improved. |
