Sorption Enhanced Mixed-Matrix Membranes by Metal-Organic Polyhedra for CO2 Separation |
| 초록 |
Polyethylene glycol (PEG) based thin film composite membranes have high gas permeability, but moderate selectivity limits their application for CO2 separation. Introducing CO2-phillic fillers in selective layer is a promising way to improve the separation properties. In present study, we have fabricated a thin film composite mixed matrix membrane through atom transfer radical polymerization with [Cu24(m-bdc)24(PEO)3(DMF)12] (EG3-MOP) nanocages as CO2-phillic filler molecules. These membranes have been well characterized and subjected to CO2 seperation studies. Due to the excellent compatibility between polymer and MOP, the thin film composite mixed matrix membrane shows enhanced separation properties towards CO2/N2/CH4 gas pairs. Particularly, EG3-MOP/PEGDMA9 membrane with 5% loading result in 50% and 15% increase selectivity of CO2/N2 and CO2/CH4 respectively, as compared to pristine composite membrane for single gas measurement. |
