Special Issue Information

Dear Colleagues,

Membrane separation processes are distinguished by their many advantages compared to other, more traditional separation methods: low-energy consumption, mild operating conditions, possibility of being integrated with conventional production/separation processes, etc. Membrane gas separation differs from other membrane technologies by its deeper roots in membrane science, material science, and polymer science. This is one of the reasons that they are developing faster than other membrane processes and traditional separation techniques. Today, a big range of membrane materials is known, and many materials are present in the market. An interesting peculiarity of membrane gas separation is that a success of a particular separation process depends both on efforts of synthetic polymer chemists, who prepare novel and efficient materials, and achievements of physical chemists, who study transport phenomena in membranes.

All these considerations were taken into account when the topic of this Special Issue was proposed: Highly-Efficient Membrane Gas Separation Materials: From Synthesis to Applications. It must give a balanced picture of the materials to which engineers have now access for solving various gas separation problems: air separation, removal of carbon dioxide from its mixtures with nitrogen and methane, separation of light hydrocarbons, extraction of helium from natural gas, etc.

Ionic liquids have attracted the attention of the industry and research community as versatile solvents with unique properties, such as ionic conductivity, low volatility, high solubility of gases and vapors, thermal stability, and the possibility to combine anions and cations to yield an almost endless list of different structures. These features open perspectives for numerous applications, such as the reaction medium for chemical synthesis, electrolytes for batteries, solvent for gas sorption processes, and also membranes for gas separation. In the search for better-performing membrane materials and membranes for gas and vapor separation, ionic liquids have been investigated extensively in the last decade and a half. This review gives a complete overview of the main developments in the field of ionic liquid membranes since their first introduction. It covers all different materials, membrane types, their preparation, pure and mixed gas transport properties, and examples of potential gas separation applications. Special systems will also be discussed, including facilitated transport membranes and mixed matrix membranes. The main strengths and weaknesses of the different membrane types will be discussed, subdividing them into supported ionic liquid membranes (SILMs), poly(ionic liquids) or polymerized ionic liquids (PILs), polymer/ionic liquid blends (physically or chemically cross-linked ‘ion-gels’), and PIL/IL blends. Since membrane processes are advancing as an energy-efficient alternative to traditional separation processes, having shown promising results for complex new separation challenges like carbon capture as well, they may be the key to developing a more sustainable future society. In this light, this review presents the state-of-the-art of ionic liquid membranes, to analyze their potential in the gas separation processes of the future. Full article

Since the discovery of polytetrafluoroethylene (PTFE) in 1938, fluorinated polymers have drawn attention in the chemical and pharmaceutical field, as well as in optical and microelectronics applications. The reasons for this attention are their high thermal and oxidative stability, excellent chemical resistance, superior electrical insulating ability, and optical transmission properties. Despite their unprecedented combination of desirable attributes, PTFE and copolymers of tetrafluoroethylene (TFE) with hexafluoropropylene and perfluoropropylvinylether are crystalline and exhibit poor solubility in solvents, which makes their processability very challenging. Since the 1980s, several classes of solvent-soluble amorphous perfluorinated polymers showing even better optical and gas transport properties were developed and commercialized. Amorphous perfluoropolymers exhibit, however, moderate selectivity in gas and liquid separations. Recently, we have synthesized various new perfluorodioxolane polymers which are amorphous, soluble, chemically and thermally stable, while exhibiting much enhanced selectivity. In this article, we review state-of-the-art and recent progress in these perfluorodioxolane polymers for gas separation membrane applications. Full article
