“…Their suitable chemical resistance, easily tunable morphology, surface properties, and catalytic functionality beside the antifouling properties of TiO 2 nanoparticles have made them applicable in membrane technology [3,9,[74][75][76][77]. The photocatalytic properties of TiO 2 nanoparticles facilitate the decomposition of organic compounds.…”

“…Silica is widely used as an inorganic additive in the fabrication of organic membranes due to its convenient operation, mild reactivity, mechanical strength, nontoxic nature, and the availability of its chemical properties [9,40,[58][59][60]. It was reported that using silica nanoparticles in different concentrations resulted in an improvement of mechanical strength [61][62][63][64][65][66] and thermal stability [67][68][69][70][71] of the host polymers.…”

“…In spite of their mechanical and chemical stability, narrower pore size distribution, higher porosity, and lower tendency to fouling in comparison with the polymeric membranes, ceramic membranes are very expensive; therefore, organic membranes are in priority for industrial applications [4]. However, the present polymeric membranes suffer from a trade-off between membrane permeability and selectivity, fouling problems and in some cases chemical resistance [5][6][7][8][9][10]. Therefore, the development of novel membranes with a combination of high permeability and selectivity beyond the trade-off line, with enhanced thermal, mechanical and chemical stability, and fouling resistance is still needed.…”

Separation using selective polymeric membranes has been well-established as an energy-efficient and cost-effective technology in water treatment and many other applications involving aqueous solutions. However, limited chemical, thermal, and mechanical resistances besides their tendency to fouling and inadequate pure water flux may often restrict their applications. To this end, inorganic materials as additives have been demonstrated to be able to enhance chemical, thermal, and fouling membrane resistances, which demonstrate their great potential for developing novel membranes by using them as additives in polymer matrices. Considering the excellent characteristics of the nano-sized particles, this study reviews the effects of inorganic nanoadditives on properties and performance of polymer/nanoparticle composite membranes. It has been demonstrated that using nanomaterials in a polymer matrix could enhance the mechanical strength and stiffness, wettability, selectivity, water permeability, and antifouling characteristics of the host polymer.

“…However, polymeric membranes have drawbacks in terms of separation performance due to the flexibility of the polymer chains limiting their ability to discriminate between specific species. The majority of polymer membranes also suffer from various ageing processes over time and can be sensitive to the cleaning agents used in the removal of fouling from the membrane surface [ 19 ].…”

Hybrid and Mixed Matrix Membranes for Separations from Fermentations

2016

Fermentations provide an alternative to fossil fuels for accessing a number of biofuel and chemical products from a variety of renewable and waste substrates. The recovery of these dilute fermentation products from the broth, however, can be incredibly energy intensive as a distillation process is generally involved and creates a barrier to commercialization. Membrane processes can provide a low energy aid/alternative for recovering these dilute fermentation products and reduce production costs. For these types of separations many current polymeric and inorganic membranes suffer from poor selectivity and high cost respectively. This paper reviews work in the production of novel mixed-matrix membranes (MMMs) for fermentative separations and those applicable to these separations. These membranes combine a trade-off of low-cost and processability of polymer membranes with the high selectivity of inorganic membranes. Work within the fields of nanofiltration, reverse osmosis and pervaporation has been discussed. The review shows that MMMs are currently providing some of the most high-performing membranes for these separations, with three areas for improvement identified: Further characterization and optimization of inorganic phase(s), Greater understanding of the compatibility between the polymer and inorganic phase(s), Improved methods for homogeneously dispersing the inorganic phase.

“…The mixed‐matrix membranes (MMMs) have proved themselves successful in achieving desired features of the membranes with enhanced overall performance (Madaeni, Ghaemi, & Rajabi, 2015). Lately, carbon‐based fillers such as activated carbon (Liu et al, 2017; Tagliavini & Schäfer, 2018), carbon nanotubes (CNTs) (Kaleekkal, Rana, & Mohan, 2016; Razmkhah, Ahmadpour, Mosavian, & Moosavi, 2017), and graphene (Ho, Teow, Ang, & Mohammad, 2017; Zhang et al, 2018) have been extensively explored for their superior features, that is, high porosity, higher adsorptive capacity, thermal stability, and high hydrophilicity.…”

The asymmetric polyethersulfone (PES‐15 wt.%) mixed‐matrix membranes were prepared by incorporation of carbon molecular sieve (CMS) with varying concentrations (1, 3, and 5 wt.%). Physicochemical characterization of synthesized membranes was carried out using field emission scanning electron microscope, atomic force microscopy, contact angle, thermogravimetric analysis, zeta potential analyzer, porosity, and mean pore sizes. Performance analysis of synthesized mixed‐matrix membranes was carried out by varying the operating parameters such as pressure (2–10 bar), feed concentration (100–1,000 mg/L), and cations type (Na+, Ca2+, Mg2+, and Sn2+). Effect of operating parameters and CMS concentration was investigated on pure water flux (PWF), permeate flux, and rejection of membranes. It was found that mixed‐matrix membrane containing 15 wt.% PES with 1 wt.% CMS displayed the superior physicochemical characteristics in terms of hydrophilicity (37.9°), surface charge (−13.8 mV), mean pore diameter (6.04 nm), and thermal properties (Tg = 218.5°C), and overall performance. E5C1 membrane showed 1.5 times higher PWF (75.5 L m−2 hr−1) and incremented in rejection for all salts than the nascent membrane. Practitioner points Carbon molecular sieve‐embedded mixed‐matrix membranes were synthesized by phase inversion method. The resultant membranes experienced improved hydrophilicity, roughness, surface charge, porosity, and mean pore diameter with 1 wt.% CMS loading. The pure water flux was improved from 55.77 to 75.05 L m−2 hr−1 when 1 wt.% CMS was added in pure PES. The observed rejection of a mixed‐matrix membrane with 1 wt.% CMS was the maximum for all salts.
