Highly permeable nanocomposite membrane for CO2 and olefin separation |
| 초록 |
We report a highly permeable poly(ethylene oxide) (PEO)/Ag nanoparticles (AgNPs)/p-benzoquinone (p-BQ) composite membrane for facilitated olefin transport and ionic liquid/Cu nanocomposite membrane for CO2 separation. The electronic structure of the AgNP and Cu NP surface was tuned by the electron acceptor p-BQ and ionic liquid to induce positive charges on the surface. The chemically activated surface is expected to form complexes with olefin or CO2 molecules, resulting in gas carrier for facilitated transport. Such facilitated transport membranes were applied for separation of olefin/paraffin or CO2/N2 mixtures. In particular, the interaction between gases and the polarized surface of metal NPs in a permeable PEO matrix or ionic liquid was expected to show excellent separation performance. |
