In this study, we investigated a poly(ether-block-amide)-5513 (PEBAX-5513)/AgBF4/ 1-butyl-3-methylimidazolium tetrafluoroborate (BMIMBF4) composite membrane, which is expected to have a high stabilizing effect on the Ag+ ions functioning as olefin carriers in the amide group. Poly(ethylene oxide) (PEO) only consists of ether regions, whereas the PEBAX-5513 copolymer contains both ether and amide regions. However, given the brittle nature of the amide, the penetration of BMIMBF4 remains challenging. The nanoparticles did not stabilize after their formation in the long-term test, thereby resulting in a poor performance compared to previous experiments using PEO as the polymer (selectivity 3; permeance 12.3 GPU). The properties of the functional groups in the polymers were assessed using Fourier transform IR spectroscopy, SEM, and thermogravimetric anal., which confirmed that the properties endowed during the production of the film using the ionic liquid can impact the performance. In the part of experimental materials, we found many familiar compounds, such as 3-Butyl-1-methyl-1H-imidazol-3-ium tetrafluoroborate(cas: 174501-65-6Quality Control of 3-Butyl-1-methyl-1H-imidazol-3-ium tetrafluoroborate)
3-Butyl-1-methyl-1H-imidazol-3-ium tetrafluoroborate(cas: 174501-65-6) is a member of lonic liquids. Actually, lonic liquids as innovative fluids have received wide attention only during the past two decades. The number of SCI papers published on lonic liquids has exponentially increased from a few in 1996 to >5000 in 2016, exceeding the annual growth rates of other popular scientific areas.
