“…Particularly for TFNcyclo-membranes, they achieve 39.0-40.6% higher pure water flux in comparison to the TFC membrane without NH2-TNTs incorporation. The results obtained in this work are in line with many previous findings [1,[5][6][7]16,[23][24], i.e. TFN membranes always achieve greater water production rate compared to TFC membrane irrespective of the solution that was used to disperse nanofillers.…”

“…A recent review authored by Lau et al [2] has summarized the effects of various types of inorganic nanomaterials on the intrinsic properties and performances of PA TFN membranes for separation processes covering not only aqueous-based media like nanofiltration (NF), reverse osmosis (RO) and forward osmosis (FO), but also for the treatment of organic solvents as well as pervaporation processes. Depending on the type and characteristics of nanomaterials used, the resultant TFN membrane could show attractive features associated with bacterial, fouling and chlorine resistance, in addition to enhancement in water flux [3][4][5][6].…”

Thin film nanocomposite (TFN) membranes containing 0.05 or 0.10 w/v% functionalized titanate nanotubes (TNTs) in polyamide selective layer were prepared via interfacial polymerization of piperazine (PIP) and trimesoyl chloride (TMC) monomers. Nanomaterials were dispersed into the monomer solution using two different approaches. In the first one, the functionalized TNTs were dispersed into the amine aqueous solution, while in the second approach the same nanomaterials were dispersed in TMC organic solution. The TFN membranes were characterized and compared with a control thin film composite (TFC) membrane to investigate the effect of nanofiller loadings and the fabrication approach on membrane properties. Results showed that introducing nanofillers into the organic phase was more effective to synthesize a TFN membrane of greater separation performance as the use of rubber roller to remove aqueous solution from the substrate surface could cause the loss of a significant amount of nanofillers, which further affected the polyamide layer integrity. It was also found that incorporation of high nanofiller loading tended to interfere with interfacial polymerization and weaken the bonds between monomers blocks, resulting in poor polyamide-nanotubes integrity. Compared to the TFC membrane, the TFN membrane made of 2% PIP and 0.15% TMC with 0.5% nanofiller incorporation could achieve greater water flux (7.5 vs 5.4 L/m 2 .h.bar) and Na2SO4 rejection (96.4% vs 86%) while exhibiting higher resistance against the fouling by protein and dye.

A review on organic–inorganic hybrid nanocomposite membranes: a versatile tool to overcome the barriers of forward osmosis

et al. 2018

Forward osmosis (FO) processes have recently attracted increasing attention and show great potential as a low-energy separation technology for water regeneration and seawater desalination. However, a number of challenges, such as internal concentration polarization, membrane fouling, and the tradeoff effect, limit the scaleup and industrial practicality of FO. Hence, a versatile method is needed to address these problems and fabricate ideal FO membranes. Among the many methods, incorporating polymeric FO membranes with inorganic nanomaterials is widely used and effective and is reviewed in this paper. The properties of FO membranes can be improved and meet the demands of various applications with the incorporation of nanomaterials. This review presents the actualities and advantages of organic-inorganic hybrid nanocomposite FO membranes. Nanomaterials applied in the FO field, such as carbon nanotubes, graphene oxide, halloysite nanotubes, silica and Ag nanoparticles, are classified and compared in this review. The effects of modification methods on the performance of nanocomposite FO membranes, including blending, in situ interfacial polymerization, surface grafting and layer-by-layer assembly, are also reviewed. The outlook section discusses the prospects of organicinorganic hybrid nanocomposite FO membranes and advanced nanotechnologies available for FO processes. This discussion may provide new opportunities for developing novel FO membranes with high performance.

“…Different nanomaterials such as graphene oxide, titanium dioxide, molecular sieve and carbon nanotube had been added to membrane structure for improving the properties of membrane such as pure water flux and anti-fouling [4][5][6][7]. Among the nanoparticles studied, graphene oxide (GO) is one of the most widely used material for preparing high-performance FO membranes due to their special properties such as unique structural properties, high chemical stability, strongly drophilicity and excellent antifouling properties [8][9][10][11][12][13].…”
