“…Surface modifications have been used in several studies to improve the permselectivity and conductivity of heterogeneous IEMs for electrodialysis and related processes . As previously explained, the heterogeneous membrane has a relatively simple preparation procedure, low production cost, and high mechanical strength (and sometimes also chemical stability) .…”

Considerable effort has been made to improve ion-exchange membrane (IEM) properties in order to achieve better performance of IEM-based processes in various applications. Surface modification is one of the effective ways to improve IEM properties. Various methods have been used to modify IEM surfaces, for example, plasma treatment, polymerization, solution casting, electrodeposition, and ion implantation. These methods are able to produce a thin and fine distributed layer and also to modify the chemical structure of the surface. The new layer can be adsorbed, deposited, or chemically bonded on a membrane surface. By using these methods, IEM properties are improved, and the desired or specific characteristics such as high monovalent ion permselectivity, low fuel crossover, and anti-organic-fouling property can be obtained. In this paper, methods for surface modification of IEMs are reviewed. Moreover, the effects of modification on IEM properties and performance are discussed.

“…Recently, the ultrasonic technology was utilized to promote the distribution of cation exchange particles in polymer binder, and had been found to reduce the aggregation of these particles and the formation of cavities . Besides, the addition of inorganic fillers into the casting solution and the surface modification by coating polymer, became the strategic sections on improving the performance of heterogeneous membranes.…”

The polystyrene-DVB/PVDF alloy particles were prepared by pulverizing the polymerization product of styrene/DVB/ PVDF in DMF, and then sulfonated with concentrated sulfuric acid to gain the cation exchange alloy powder, which was directly thermoformed by a hot-press machine to form the titled cation exchange alloy membranes with the structure of semi-interpenetrating polymer network. The effects of the polystyrene-DVB to PVDF mass ratio and the DVB content in the monomers on the physical and electrochemical properties of the prepared alloy membranes were investigated. While the Fourier transform infrared spectroscopy (FTIR) confirms the components of membranes, the scanning electron microscopy (SEM) reveals that the alloy membranes possess a uniform distribution of functional groups, and a more dense structure with the increases of DVB content and PVDF content. The optimal prepared membranes have the area electrical resistance values within 3.0-6.6 XÁcm 2 , obviously superior to the commercial heterogeneous cation exchange membrane, as well as the moderate water contents of 35-40% and the desirable permselectivity with a transport number more than 0.95.

“…In this case, the magnetic field induces the alignment of a magnetic ion-exchange nanoparticle. Recently, sonication is used in several works on preparations of heterogeneous IEM [55,[80][81][82][83][84][85]. They observed that sonication has a significant influence on resin particle distribution in membrane matrix, can help to break particle aggregation and provide the possibility to make a uniform phase.…”

Abstract. Extensive application of synthetic ion-exchange membrane (IEM) in many areas has necessitated the improvement of their properties. Recently, the introduction of nanoparticles into polymeric membrane has attracted growing interest since the combination of both materials results in better properties. This well-known mixed-matrix membrane exhibits superior characteristics compared to an individual polymeric membrane. Properties of the nanoparticles such as electrical conductivity, hydrophilicity, and adsorption capacity can be utilized to produce the IEM with better physicochemical, electrochemical, and mechanical characteristics. The nanoparticles may also be used to achieve a specific characteristic such as an antibacterial property and monovalent ion permselectivity. In this paper, preparation, the role of inorganic materials and performance of mixed-matrix IEM are reviewed. In addition, challenges facing mixed-matrix IEM and strategies taken to overcome those challenges and future perspectives are discussed.
