Nanoengineered electrospun fibers and their biomedical applications: a review

Surface functionalization of nylon 66 membrane using para-phenylenediamine and carboxylic functionalized multi-walled carbon nanotubes for removal of calcium ions from aqueous solution

“…Among them, the ultrafiltration and nanofiltration are usually used for early steps to separate and/or purify chitin from raw protein solution. Commonly used membranes in these methods are porous polymeric films or the thin film composites (TFCs) based on them [6][7][8][9][10][11][12][13][14][15][16]. Liquid flows, including semi-finished or finished liquids, washing water, wastewater, are pumped and returned to high pressure in the production line [9][10][11][12].…”

“…Multilayered TFN membranes are often casted from nanocomposites or formed directly during the polymerization of the precursors. Nanomaterials are dispersed in thin films to generate or improve mechanical, chemical and special properties combined from different groups of materials (such as hydrophilic properties, creating interactive forces, static electricity, adsorption capacity, specific surface area, … ) [7,10,[13][14][15][16][17][18][19][20][21][22][23][24]. Therefore, multilayered TFN membranes have a diverse range of segregation, according to the purpose of use, and enhanced anti-fouling features.…”

“…Now, such TFN membranes have begun to appear on the market with a wide range of features and applications. A number of researches focus on solving these two problems by using new materials and their composites, including flexible polymeric thin films [12][13][14] or inorganic porous solids [13,19]. Polymeric membranes are more widely developed than the rest of the materials due to their low production costs, mass production and flexible applications [5,19].…”

“…Polymeric membranes are more widely developed than the rest of the materials due to their low production costs, mass production and flexible applications [5,19]. Types of polymer materials commonly used to make membranes include polytetrafluoroethylene (PTFE) [21,23], polyvinylidene fluoride (PVDF) [9,11,13,23], polyamide (PA) [14,15,17,19,21], polysulfone (PSF) [14,15,17,24], polyethersulfone (PES) [15,19,20], polyetherimide (PEI) [11,15,24], polystyrenes (PS) [14], polyvinyl alcohol (PVA) [14,16], … Among such materials, PA based thin-film nanocomposite (PA-TFC) are commonly used as either forward osmosis (FO) or reverse osmosis (RO) membranes due to their high separation efficiency, high mechanical strength and environmental friendliness [23,24]. However, the fouling is easily caused by hydrophobicity of the active PA layer as well as uncertain retention time of components on rough walls of pores.…”

Photocatalytic Degradation of Methylene Blue Dye by Electrospun Binary and Ternary Zinc and Titanium Oxide Nanofibers

“…Electrospinning (ES) is a simple and cost-effective technique widely utilized for the growth of high aspect-ratio and surface-area (organic, inorganic, and hybrid) nanostruc-tures with different morphologies [37][38][39] used in a great variety of applications ranging from energy conversion and storage, to biomedicine, gas sensing, and water remediation [37,[40][41][42][43]. ES scalability and the availability of commercial machineries capable of producing fibrous sheets of up to 300-600 m 2 in size make it a suitable technique for the production of NF catalysts on an industrial scale.…”
