Reverse CO2/N2 selectivity membranes based on microporous organic molecular network/polyimide nanocomposite |
| 초록 |
We synthesized microporous nanocomposites by controlling the interplay between phase separation and sol-gel transition in mixture of organic molecular networks(OMNs) and polyimide. The OMNs can generate nanochannels via thermal rearrangement of urea groups. The polyimide domains dispersed in the OMNs matrix provide dimensional stability against thermal deformation. Thin membranes of the OMNs/PI nanocomposites exhibit reverse selectivity: the observed CO2/N2 selectivity was about 0.15 in sharp contrast with that known in the conventional polymer membrane of 3~100. This work was supported by the Basic Science Research Program (2010-0000282) through the National Research Foundation of Korea (NRF) funded by the Ministry of Education, Science and Technology (MEST). |
