“…Since the ion flux is determined by the product of the charge carrier concentration and their diffusion coefficient, the rate of non-selective transfer also increases rapidly with increasing water uptake. Thus, the membrane conductivity improvement is most often accompanied by increase in undesirable transfer of coions and nonpolar molecules that decreases the membrane selectivity [ 81 , 82 , 83 , 84 ]. This relationship will be addressed in detail below.…”

“…This is due to the fact that the limitation of the swelling of the hydrophilic ionic domains is accompanied by an increase in their selectivity. Another important parameter is the amount of functional groups [ 82 , 136 , 139 , 140 ]. For example, an increase in the sulfonation degree of polystyrene in the cation-exchange membranes based on block copolymers from 12 to 49% leads to an increase in water uptake from 3 to 165 water molecules per sulfonic-acid group.…”

“…For anion-exchange membranes, the nature of the functional group represented by various quaternary amines is especially relevant [ 82 , 141 ]. Therefore, Cho et al [ 82 ] showed that AEM based on substituted imidazoles have higher selectivity than those with the trimethylamine functional groups, which was associated with their lower hydration degree.…”

Nowadays, ion-exchange membranes have numerous applications in water desalination, electrolysis, chemistry, food, health, energy, environment and other fields. All of these applications require high selectivity of ion transfer, i.e., high membrane permselectivity. The transport properties of ion-exchange membranes are determined by their structure, composition and preparation method. For various applications, the selectivity of transfer processes can be characterized by different parameters, for example, by the transport number of counterions (permselectivity in electrodialysis) or by the ratio of ionic conductivity to the permeability of some gases (crossover in fuel cells). However, in most cases there is a correlation: the higher the flux density of the target component through the membrane, the lower the selectivity of the process. This correlation has two aspects: first, it follows from the membrane material properties, often expressed as the trade-off between membrane permeability and permselectivity; and, second, it is due to the concentration polarization phenomenon, which increases with an increase in the applied driving force. In this review, both aspects are considered. Recent research and progress in the membrane selectivity improvement, mainly including a number of approaches as crosslinking, nanoparticle doping, surface modification, and the use of special synthetic methods (e.g., synthesis of grafted membranes or membranes with a fairly rigid three-dimensional matrix) are summarized. These approaches are promising for the ion-exchange membranes synthesis for electrodialysis, alternative energy, and the valuable component extraction from natural or waste-water. Perspectives on future development in this research field are also discussed.

Salinity gradient energy is currently attracting growing attention among the scientific community as a renewable energy source. In particular, Reverse Electrodialysis (RED) is emerging as one of the most promising membrane-based technologies for renewable energy generation by mixing two solutions of different salinity. This work presents a critical review of the most significant achievements in RED, focusing on membrane development, stack design, fluid dynamics, process optimization, fouling and potential applications. Although RED technology is mainly investigated for energy generation from river water/seawater, the opportunities for the use of concentrated brine are considered as well, driven by benefits in terms of higher power density and mitigation of adverse environmental effects related to brine disposal. Interesting extensions of the applicability of RED for sustainable production of water and hydrogen when complemented by reverse osmosis, membrane distillation, bioelectrochemical systems and water electrolysis technologies are also discussed, along with the possibility to use it as an energy storage device. The main hurdles to market implementation, predominantly related to unavailability of high performance, stable and low-cost membrane materials, are outlined. A techno-economic analysis based on the available literature data is also performed and critical research directions to facilitate commercialization of RED are identified.

“…Mechanical properties of the prepared membranes with the same monomer are enhanced with the decreasing IECs due to the plasticizing effect of the absorbed water, similar behavior has been observed in PEMs. The tensile strengths of the x C‐ y ‐Q membranes are closed to the published poly(arylene ether sulfone)s AEMs DIm‐PAES and TMA‐40‐PAES, side‐chain‐type AEMs PMP‐TMA‐41, and ImPES‐0.45 . The 4C‐50‐Q and 8C‐60‐Q membranes showed good tensile strength approximate to Nafion‐117, indicating their potential of applying in AEMFCs.…”

Poly(arylene ether sulfone)s containing symmetric side‐chain benzyltrimethyl ammonium groups are synthesized via Suzuki reaction, copolycondensation, and functionalization. Two series of anion exchange membranes, 4C‐y‐Q and 8C‐y‐Q, containing four or eight pendent benzyl or cationic groups are synthesized to clarify the steric effect of the benzyl groups on the water channels. 1H NMR and transmission electron microscopy are used to study the chemical structure and morphology, respectively. These two series of membranes are assessed in terms of ion exchange capacity (IEC), water uptake, swelling ratio, λ, hydroxide ion conductivity (σ ), mechanical properties, thermal stability, and alkaline stability. The 4C‐y‐Q membranes show better‐defined microphase separation morphology and higher ion conductivity (206.2 mS cm−1 at 80 °C) than most of the reported membranes. Ionic conduction efficiency (σ/IEC) can be improved and made higher than that of Nafion with lower ion transport activation energy. The obtained membranes with superior properties reveal their prospective application in anion exchange membrane fuel cells.
