| titleOfInvention | For N2/CH4Separated gas separation membrane |
| abstract | The invention relates to a gas separation membrane technologyIn particular to a method for N 2 /CH 4 A separated gas separation membrane. The separation membrane is formed by free radical polymerization between carbon-carbon double bonds, contains a large amount of fluorine atoms except carbon atoms, and is formed by reducing CH 4 The solubility of (2) and the dissolution selectivity are improved, and the N content of the separation membrane can be improved 2 /CH 4 Separation performance. The preparation method comprises the following steps: mixing the monomer with high fluorine content and the cross-linking agent, adding the initiator, coating the mixed solution on a support, and obtaining the separation membrane through free radical polymerization between carbon-carbon double bonds. |
