“…The highly ordered particle yields in the improvement of IEM properties. The improved IEM properties with the improved particle distribution are also reported as a result of applying magnetic field [79]. In this case, the magnetic field induces the alignment of a magnetic ion-exchange nanoparticle.…”

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.

“…The fabrication of anisotropic membranes orientated in the desired direction in a matrix is an attractive idea to enhance ionic conductivity. Two methods to design anisotropic nanocomposite membranes are to align nanofillers in the matrix under electric field (Oren et al, 2004) or magnetic field (Brijmohan and Shaw, 2007). In a study, SGO⁄Fe3O4 nanosheets were aligned under magnetic field in PVP matrix by .…”

“…Magnetite is highly preferred for many applications such as drug carrier [2], drug release [3], cancer therapy [4], a proton exchange membrane [5] and the heavy metal adsorbent [6]. Main advantage of using magnetic adsorbent is that the magnetic adsorbent is nontoxic and can be reused and easily separated from the solution by an external magnet [7].…”

Abstract-It has been examined the physical and chemical properties of magnetite synthesized mechanically and sonochemically by co-precipitation and reverse co-precipitation methods. Ammonia solution was used as precipitating agent to adjust the pH of the suspension to reach 11. Characterization of the synthesized magnetites was conducted using the Fourier Transform Infrared Spectroscopy (FTIR), the X-ray diffraction (XRD), Scanning electron microscopy (SEM), and Vibrating Sample Magnetometer (VSM). The characterization results showed that the crystallinity of magnetites synthesized by the ordinary mechanically assisted co-precipitation was higher than that of magnetites synthesized by mechanically assisted reverse-co-precipitation. The involvement of sonochemical treatment instead of mechanical treatment gave smaller and more homogeneous crystal size. The morphology of magnetites was spherical and agglomerated with homogeneous size distribution.
