Novel Ionic Liquids Supported Membranes: A Review

Tejas T. Shetiye, Shamli S. Chavan, Swapnil A. Dharaskar

Abstract


In this work, a supported ionic liquid membrane (SILM) can be prepared by impregnating different types of polymers with suitable novel phosphonium-based ionic liquids (ILs). ILs have reached an enormous interest as CO2 solvents and other engineering applications due to their unique properties such as negligible vapour pressure and selectivity, making them very attractive in order to obtain stable supported liquid membranes. This work can appraise the preparation and use of a new class of supported liquid membranes. ILs are compounds that typically contain organic cations and inorganic anions with unique properties. These ILs can be synthesized by the reaction of phosphonium-based salts with different hydrogen bond donors. Phosphonium cations based ILs are a readily available family of ILs that in some applications after superior properties as compare to Nitrogen cation based ILs. These are used as Extraction solvents, Chemical synthesis solvents, electrolytes in batteries and in super capacitor-anion combinations that are available commercially. Here, we provide an overview of the properties of these interesting materials and their diverse applications. An evaluation of the membrane stability was carried out for stable SILMs can be experimentally determined.
