Mixed strategy has been widely utilized to design novel membranes or tailor membrane structure, however the construction of facilitated transport membranes (FTMs) with mixed strategy has rarely been reported. In this work, eight kinds of mixed protic ionic liquid (MPIL) derived FTMs (MPIL-FTMs) were designed with mixed strategy for highly efficient ethylene/ethane separation by impregnating MPILs and ethylene transport carrier into porous support. The morphol. of MPIL-FTMs were characterized by SEM and AFM, and their mol. interactions were investigated by 1H NMR, FTIR and DSC. The MPIL-FTMs exhibited long-term stability and various ethylene permeability-ethylene/ethane selectivity combinations, which indicated mixed strategy could easily customize the separation performances of MPIL-FTMs. Moreover, a fundamental law for mixed strategy was obtained that the two parent PILs with similar chem. structure and mol. interactions favored the synchronous improvement of C2H4 permeability and C2H4/C2H6 selectivity. For example, the C2H4 permeability of the [BA][Pyr][NO3] derived MPIL-FTM reached up to 561.0 Barrer with improved C2H4/C2H6 selectivity of 26.7, which were superior to most of reported membranes, thus breaking through the ubiquitous trade-off effect. This study proves the mixed strategy is a promising platform for the design of high-performance FTMs as well as their structure modification, and the marriage of mixed strategy with diversity of ILs creates enormous opportunities to construct advanced membranes for energy-intensive gas separations This study involved multiple reactions and reactants, such as 2-Methoxyethylamine (cas: 109-85-3Recommanded Product: 2-Methoxyethylamine).
2-Methoxyethylamine (cas: 109-85-3) belongs to ethers. Esters typically have a pleasant smell; those of low molecular weight are commonly used as fragrances and are found in essential oils and pheromones. Liquid esters of low volatility serve as softening agents for resins and plastics. Esters also include many industrially important polymers. Polymethyl methacrylate is a glass substitute sold under the names Lucite and Plexiglas; polyethylene terephthalate is used as a film (Mylar) and as textile fibres sold as Terylene, Fortrel, and Dacron.Recommanded Product: 2-Methoxyethylamine
