“…In the initial development of MMMs, only nearly spherical microporous materials were used as fillers [26,31]. In recent years, low-dimensional (1D and 2D) porous materials, such as nanotubes (1D) [32][33][34][35] and layered porous materials (2D) [36][37][38], have been regarded as emerging filler materials. Layered porous materials could potentially outperform near-spherical ones for use as filler in MMMs, for two reasons.…”

“…Most polymeric membranes are often prepared from the same materials, but under various membrane formation conditions, according to the required membrane type [1][2][3]. The polymeric materials such as poly(vinylidene fluoride), Polysulfone, Polyethersulfone, poly (acrylonitrile), and poly(vinyl chloride) copolymers are used to produce UF and MF membranes.…”

“…RO and NF membranes are made of cellulose acetate, tricellulose acetate, Polyethersulfone, or Polysulfone coated with aromatic polyamides. Recently, the production of cheap antifouling RO membranes is required to serve the global demands for water desalination [1][2][3]. Blending of polymers with nanomaterials is a modern technological way for providing excellent polymeric membranes with set of desired properties at the lowest cost such as a combination of strength and toughness, impact strength or solvent resistance, and good performance [3][4][5].…”

“…The most common methods to functionalize the nanomaterials on the membrane surface are expressed as follows: vapor deposition, electrophoretic coating, and dip coating, based on deposition of nanomaterials on the membrane surface. The blending method depends on the introduction of the nanomaterials on the backbone of the polymeric membrane; therefore the stability of the nanomaterials on the blending membranes has been achieved compared with precipitation methods [2][3][4][5][6][7][8][9][10][11][12].…”

This study describes the preparation, characterization, and evaluation of performance of blend Polyethersulfone (PES) with manganese(III) acetylacetonate Mn(acac)3to produce reverse osmosis blend membrane. The manganese(III) acetylacetonate nanoparticles were prepared by a simple and environmentally benign route based on hydrolysis of KMnO4followed by reaction with acetylacetone in rapid stirring rate. The prepared nanoparticle powder was dissolved in polymer solution mixture to produce RO PES/Mn(acac)3blend membrane, without any treatment of Polyethersulfone membrane surface. The membrane morphology, mechanical properties, and performance were presented. The scanning electron microscopy (SEM) images have displayed a typical asymmetric membrane structure with a dense top layer due to the migration of Mn(acac)3nanoparticles to membrane surface during the phase inversion process. Contact angle measurements have indicated that the hydrophilicity of the membrane was improved by adding Mn(acac)3. AFM images have proved excellent pores size distribution of blend membrane and lower surface roughness compared with bare PES. The desalination test was applied to blend membrane, where the blend membrane provided good performance; particularly, permeate flux was 24.2 Kg/m2·h and salt rejection was 99.5%.

The use of nanoparticles to make nanocomposite membranes for water treatment spans a range of development with the majority of materials existing at lab scale, some having been piloted, and a select few at commercial scale. As such, the use of nanomaterials in this field is still in the early stages. There is a large parameter space to explore, which includes the many types of polymers used in membranes, the wide range of membrane types used in water separations, the great variety of nanomaterials and their properties, and the multitudinous ways in which nanomaterials can be added to polymers. Determining which polymer nanoparticle combination will deliver substantially improvement over the bare polymer is challenging, but attempting to predict how nanomaterials will impact the desired membrane and flux characteristics when incorporated into a polymer and formed into a membrane is even more difficult due to the complex thermodynamics and kinetics that occur between polymers and nanoparticles during membrane synthesis. Further, optimizing the interactions of nanoparticles with polymer systems is not trivial, but is critical to translating the nanomaterial properties to the polymer matrices in order to produce enhanced membranes. These challenges are opportunities to produce nanocomposite membranes with enhanced practical applications.
