Nanoparticles functionalized ceramic membranes: fabrication, surface modification, and performance

Utilization of a mixed matrix membrane modified by novel dendritic fibrous nanosilica (KCC-1-NH-CS2) toward water purification

“… 4 With the advancement of nanotechnology, widespread studies have been conducted to use the benefits of ceramic nanomaterials in polymeric membranes to overcome their disadvantages. 27 Thus, a new class of nanocomposite membranes containing inorganic fillers has been developed, which are called Mixed Matrix Membranes (MMMs). 28 A variety of nanomaterials including carbon nanotubes (CNT), graphene, quantum dots, different clays, metal oxides, SiO 2 , and Al 2 O 3 have been used in nanocomposite membranes.…”

Optimizing and control of effective synthesize parameters for Fe3O4 nanoparticles using response surface methodology

“…They can be used to treat wastewater contaminated by heavy metals such as Cadmium (II), Chromium (VI) and Copper (II) (Chen et al 2017;Ewis et al 2020;Hajizadeh et al 2020;Matome et al 2020). The advance in terms of combining nanotechnology and membrane technology has greatly expanded the use of Fe 3 O 4 NPs by introducing them as nanofillers in membrane modification and concurrently enhancing the membrane application for wastewater treatment (Ba-Abbad et al 2017;Daraei et al 2013;Ewis et al 2021). However, it is crucial to obtain high reactivity ultrafine Fe 3 O 4 NPs with higher ratio of surface area to volume (Tang and Lo 2013).…”

Development of Hydrophilic Polylactic Acid Hollow-Fiber Membranes for Water Remediation

“…Membrane separation process is one of the most effective techniques to solve the water issues and has been widely deployed in various fields such as chemical engineering, food engineering and pharmaceutical industry as well. − Up to now, the most membranes were prepared using polymeric materials such as polyamide (PA), polyvinylidene fluoride (PVDF), poly­(ether sulfone) (PES), and cellulose acetate fiber (CA), whose features include easy processing, low cost, and excellent separation. − Nevertheless, because of their poor biodegradability, waste membranes always cause secondary environmental problems, which are increasingly taken into account and researched. − Ceramic materials were believed as an alternative that was easily regenerated at a high temperature. However, the high cost of ceramic materials hampers the wide application of ceramic membranes. , Most recently, biodegradable polymers have attracted lots of attention since they could be degradable with certain specific microorganisms or proteins while quite stable under service conditions. − PLA is such a kind of biodegradable polymeric materials that has been widely deployed in a wide range of medical applications. ,− Because PLA contains plenty of hydrophobic functional groups such as methyl groups and ester groups, it shows strong hydrophobic property . This always leads to serious fouling when applied as separation membranes. , Several attempts have gone into reducing the hydrophobicity of PLA nanofiber membranes and the membrane fouling through tailoring the surface roughness, − for example, introducing hydrophilic functional groups by incorporating TiO 2 nanoparticles.…”
