Mixed Matrix Membranes Consisting of Graft Copolymer and Mesoporous Metal Oxides |
| 초록 |
A series of graft copolymer such as poly(vinyl chloride)-g-poly(oxyethylene methacrylate) (PVC-g-POEM) was synthesized via atom transfer radical polymerization (ATRP). Mesoporous perovskite with a high porosity and interfacial properties were synthesized via a solvothermal reaction using PVC-g-POEM as a structure-directing agent. A PVC-g-POEM graft copolymer with a worm-like morphology was utilized as a soft matrix to prepare a mixed matrix membrane with mesoporous perovskite through a solution-casting method. The permeability of MMM with MgTiO3 was greater than those of MMM with only MgO or TiO2, indicating the simultaneous improvement of solubility and diffusivity in the former, as supported by CO2 temperature-programmed desorption measurements. The MMM with MgTiO3 25wt% exhibited a CO2 permeability improvement of 140% up to 138.7 Barrer without a large loss of CO2/N2selectivity. |
