Polyionic liquid membrane: Recent development and perspective

Organic iontronic memristors for artificial synapses and bionic neuromorphic computing

“…63,64 Due to their exceptional chemical stability and precise control over ions, ionic liquids have also been extensively studied and applied in the fields of solar cells and flexible fuel cells, while they can also be prepared into thin films for metal protection, electronic device packaging, biomedicine, and so on. 65–67 In addition, OIMs can be applied in the domains of configurable circuits and multilevel memory, owing to their adjustable molecular structure, excellent optoelectronic properties, large specific surface area, controllable porosity, etc . 68–70 Overall, the unique characteristics of OIMs enable them to exert excellent performance and application in diverse fields, thereby manifesting their significance for further development and investigation in the future.…”

Ionic liquids membranes for liquid separation: status and challenges

“…The recent advances in PILMs for CO 2 separation have been well documented and different types of PILMs have been prepared including PIL-polymer membranes, PIL/IL composite membranes, and PIL-based mixed matrix membranes. 74,75 In PILMs, the imidazolium cations are often tethered as side chains to the poly(acrylate) or poly(styrene) backbone, creating a network of ionic bonds, which is responsible for the high mechanical stability. The fabrication strategy of PILMs is similar with that of ILGMs subject to the synthesis of PILs.…”

CO2-Philic Imidazolium-Based Poly(Ionic Liquid) Composite Membranes for Enhanced CO2/N2 Separation

“…PILs as novel materials have been widely employed in thermal-responsive materials, carbon materials, catalysis, porous polymers, separation, and adsorption materials. , PILs are synthesized from the IL monomers which combine ILs with other polymers to create macromolecular structures. − Among them, ILs are described as molten salts, which are composed of cations and anions and exist in a liquid state at a temperature below 100 °C . Due to the designability of cations and anions existing in ILs, the properties of ILs can be tuned by adjusting the chemical structures of ILs. , Further, some important progress in using ILs to prepare IL-based membranes for CO 2 separation has been achieved and summarized in the previous literature. − Qazi et al explored the potential of combining ILs 1-ethyl-3-methylimidazolium ethylsulfate and hollow fiber membrane contactors for CO 2 capture, providing a novel method to obtain high efficiency due to the high CO 2 solubility and physical absorption behavior of 1-ethyl-3-methylimidazolium ethylsulfate . Vu et al minimized the nonselective interfacial defects of mixed matrix membranes (MMMs) by coating a thin layer of three different imidazolium-based ILs, and the combination of MOFs and ILs is proposed as a potential method to address the interfacial issue in MMMs, particularly enhanced gas selectivity .…”
