“…were designed and synthesized in recent years, which were featured with large specific surface area, high porosity and good interconnectivity. [12][13][14][15][16][17][18][19] However, according to the previous literatures, nanofibrous film for sensing Zn 2+ was rarely reported. So synthesize a functionalized electrospun nanofibrous film with high sensitivity and selectivity toward Zn 2+ is very valuable.…”

A novel nanofibrous film chemosensor was fabricated by copolymerization and electrospinning, which exhibited signaling behaviors for Zn 2+ . Upon addition of Zn 2+ , the sensor film exhibited obvious fluorescence enhancement in a linear fashion. Owing to a larger surface area and high permeability, the selectivity and sensitivity of the nanofibrous film for Zn 2+ were satisfactory and achieving a limit of detection of 1.95 × 10 -5 mol L -1. Moreover, this material could serve as an adsorbent for Zn 2+ , as the adsorption capacity was 11.45 mg of Zn 2+ ions per gram of nanofibrous film.

“…[11][12][13][14] Electrospun fibers of poly(methyl methacrylate) (PMMA) and ethyl cellulose with N-3-(4-(dimethylamino phenyl)allylidene)isonicotinohydrazide as an embedded fluorophore showed 6-10-folds higher in sensitivity to Cu 21 than those of the continuous thin films. 15 Wang et al 16 reported a highly responsive optical fiber sensor for Fe 31 , Hg 21 , and 2,4-dinitrotoluene based on immobilizing pyrene methanol to poly(acrylic acid). Pyrene was chosen as a fluorescent indicator due to its large Stokes shift, high-quantum yield, strong absorbance, excellent photostability and lifetime, and relatively nontoxicity.…”

Electrospun fibers for ferric ion (Fe 31 ) detection were prepared from solutions of poly(methyl methacrylate) (PMMA), poly(vinyl chloride-co-vinyl acetate-co-vinyl alcohol) ((90 : 4 : 6), PVC terpolymer), and pyrene. The effects of PVC terpolymer content (0,10,20, 30, and 40% by weight of PMMA) and electrospinning conditions on fiber size and morphology were studied using scanning electron microscopy. Uniform fibers were obtained from all compositions, and fiber sizes slightly increased with PVC terpolymer content. At 40% PVC, fiber breakage and pyrene clusters were observed. The suitable pyrene content in electrospun fibers was found to be 20%. The ratio of fluorescence intensities of fibers with 30% PVC and 20% pyrene before and after (F 0 /F) immersion in 1.0 mM Fe 31 solution was 1.36.

“…The presence and concentration of the heavy metals can therefore be traced and removed at fairly low concentrations. Several biobased nanofibres such as ethyl acetate, cellulose acetate and cellulose have been functionalized with different fluorescent compounds to detect Cu [260][261][262]; Cr [260], Fe [263] and Hg ions [261,264]. Due to the large surface areas of the electrospun nanofibres, the sensitivity, selectivity, response time, and stability were enhanced.…”

Abstract. Over the past decades, electrospinning of biopolymers down to nanoscale garnered much interest to address most of the millennia issues related to water treatment. The fabrication of these nanostructured membranes added a new dimension to the current nanotechnologies where a wide range of materials can be processed to their nanosize. Electrospinning is a simple and versatile technique to fabricate unique nanostructured membranes with fascinating properties for a wide spectrum of applications such as filtration and others. These nanostructured membranes, fabricated by electrospinning, were found to be of a paramount importance because of their advanced inherited properties such as large surface-to-volume ratio, as well as tuneable porosity, stability, and high permeability. The extensive research conducted on these materials extended the success of electrospinning not only to bio-based polymer nanofibres, but to their hybrids and their derivatives. The technique also created avenues for advanced and massive production of nanofibres. This paper reviews the recent developments in the electrospinning technique. Electrospinning of biopolymers, their blends and functionalization using metals/metal oxides, and the potential applications of electrospun nanofibrous membranes in water filtration are discussed.
