High-Selectivity CO2 Mixture Separations by a Guanylated Polymer of Intrinsic Microporosity (PIM-G) Membrane
Membrane technology has the potential to replace thermal methods for gas separation, resulting in significant energy savings. However, materials with better combinations of permeability and selectivity are needed to fulfill industrial requirements. In this work, we functionalize a polymer of intrinsic microporosity with a high CO2 affinity guanidinium moiety to produce a highly CO2-permselective ionic polymer (PIM-G). Permeability–selectivity performance is compared under pure- and mixed-gas conditions for CO2/CH4, CO2/N2, and CO2/O2 gas pairs. In addition, counteranion identities are modified along the halide series (F–, Cl–, Br–, and I–) to optimize separation performance, with larger halides found to improve the CO2 permselectivity without a commensurate drop in the CO2 permeability.
期刊介绍:
Macromolecules publishes original, fundamental, and impactful research on all aspects of polymer science. Topics of interest include synthesis (e.g., controlled polymerizations, polymerization catalysis, post polymerization modification, new monomer structures and polymer architectures, and polymerization mechanisms/kinetics analysis); phase behavior, thermodynamics, dynamic, and ordering/disordering phenomena (e.g., self-assembly, gelation, crystallization, solution/melt/solid-state characteristics); structure and properties (e.g., mechanical and rheological properties, surface/interfacial characteristics, electronic and transport properties); new state of the art characterization (e.g., spectroscopy, scattering, microscopy, rheology), simulation (e.g., Monte Carlo, molecular dynamics, multi-scale/coarse-grained modeling), and theoretical methods. Renewable/sustainable polymers, polymer networks, responsive polymers, electro-, magneto- and opto-active macromolecules, inorganic polymers, charge-transporting polymers (ion-containing, semiconducting, and conducting), nanostructured polymers, and polymer composites are also of interest. Typical papers published in Macromolecules showcase important and innovative concepts, experimental methods/observations, and theoretical/computational approaches that demonstrate a fundamental advance in the understanding of polymers.
