BACKGROUND Copper nanoparticles (CuNPs) are studied for the design of advanced nanocomposite membranes owing to their highly antimicrobial properties, specific catalytic and chemical activities, abundancy and low cost. In this work, thin film nanocomposite membranes (TFN) containing CuNPs in the polyamide (PA) layer were designed via a facile interfacial polymerization method. The nanoparticles were incorporated into an aqueous solution containing piperazine monomers which is poured on the top surface of the polyethersulfone ultrafiltration membrane followed by adding trimesoyl chloride to form a polymerized PA film. RESULTS The results show that the surface morphological structure investigated by scanning electron microscopy and atomic force microscopy images is subject to visible changes of surface morphology, with a rougher net‐like structure while analysis of the chemical structure using attenuated total reflection–Fourier transform infrared spectroscopy confirms that the introduction of CuNPs did not impede the structure of the PA layer. The effect of addition of inorganic functionalized nanomaterials on the overall membrane performance was significant. The water flux was greatly increased (twice the original water permeability), while maintaining high retention of Na2SO4, demonstrating good performance in the range of nanofiltration (NF). Furthermore, the TFN membranes exhibited a specific antibacterial effect, reducing the number of living bacteria (Escherichia coli) by 94.0%. CONCLUSION Inorganic functionalization using CuNPs in the aqueous phase strongly enhanced membrane performance and provided the membrane surface with antimicrobial properties. This study suggests a new approach to TFN membrane research for the design of NF membranes for water treatment. © 2018 Society of Chemical Industry

Using interfacial polymerization (IP) of m‐phenylenediamine aqueous solution containing polyoxovanadate nanoclusters (POV) and trimesoyl chloride (TMC) in organic solution, we fabricated a novel polyamide (PA)‐ polyoxovanadate nanocluster (POV) nanocomposite membranes (PA‐POV TFN). The chemical structures and morphologies of the synthesized membranes were characterized by Fourier transform infrared (FTIR) spectroscopy, atomic force microscope (AFM), scanning electron microscopy (SEM) and water contact angle measurements. Experimental results showed that the performances of PA‐POV TFN membranes are remarkably dependent on POV incorporation in the membranes, which could be controlled by using different amounts of POV particles. Moreover, the PA‐POV TFN membranes illustrated outstanding antibacterial properties against Gram‐negative E. coli. On the other hand, the incorporation of various amounts of POV in the membranes improved the membrane separation performances (water flux and salt rejection) as well as the antibacterial activity in FO process as compared to the original thin‐film composite (TFC) polyamide membrane.

their energy consumption is much lower than that of thermal approaches. [3] Therefore, membrane technologies are regarded as cost-effective candidates and play an increasingly important role in the treatment of natural waters and wastewaters. [4] Membrane processes for water purification and desalination can be generally classified into microfiltration (MF), ultrafiltration (UF), nanofiltration (NF), reverse osmosis (RO), and emerging forward osmosis (FO) according to the pore size of the membrane and the respective rejection mechanism. The materials used to fabricate the membranes cover a wide range of polymers and inorganic materials. By far, polymeric membranes are the most widespread type due to their high processability, high flexibility, and low cost. [5][6][7] Traditional asymmetric membranes that contain only one type of polymer are mainly used for UF and a few NF applications. These membranes exhibit an asymmetric porous structure that consists of a thin nano porous active layer and a microporous underlying layer. MF membranes, however, possess a relatively symmetric micro porous structure. These porous membranes are mainly fabricated by phase inversion. For RO, FO, and most NF membranes that reject nanoscale solutes, an individual nonporous, dense, and thin polyamide (PA) active layer is normally required and is deposited onto a porous support layer to ensure a high selectivity. The active layer is prepared via interfacial polymerization (IP), while the support layer can be fabricated by phase inversion. These membranes are known as thin film composite (TFC) membranes, and the layers are comprised of different polymers. TFC membranes possess superior permeability over that of first-generation cellulose acetate membranes. [8,9] Although polymeric membranes have been widely reported in scientific studies and utilized for industrial applications, they are restricted by the inherent limitations of the material, such as a permeability/selectivity trade-off and a low fouling resistance. The current ability to control the membrane structure in both molecular-level design and fabrication process is not satisfactory. [10] In the last decade, the incorporation of nanomaterials into polymeric membranes has gained considerable attention owing to the potential of the resulting materials for overcoming the above limitations. [11,12] These advanced composite membranes have shown enhanced performance with a low loading of nanoparticles (NPs), including zeolites, [13][14][15] silica, [16][17][18][19][20][21][22] Membrane technologies for water treatment and desalination are increasingly developed and utilized to address the global challenges of water security and supply. Membrane-based separations can produce water with desirable qualities from a wide range of water sources, such as groundwater, seawater, brackish water, and wastewater. However, the membranes, which are typically made from polymers, are still restricted by their inherent limitations, including a permeability/selectivity trade-off and a high fouling prop...
