“…Some researchers used the nanofibers as carriers of adsorbents, and poly (vinyl alcohol) (PVA) was the most common one. Various adsorbents, including poly (acrylic acid), graphene oxide, polyethyleneimine, and chitosan, had been coated on the PVA membranes; these adsorbent membranes had high adsorption capacity in multiple consecutive cycles (Yan et al 2015;Xing et al 2017;Zhu et al 2017;Habiba et al 2017a (Zhou et al 2016b;Li et al 2017b).…”

Materials of nanofibrous morphology and structure are attractive for solving environmental problems including water-related issues. In recent years, increasing interest is geared on the use of specially designed electrospun nanofibers for water/wastewater treatment applications. The nanofibers can be used in the form of nonwoven structures, as stand-alone membranes, as support layer or as a surface modification layer that enables added functionality to a composite material. Continuous research has been carried out in optimizing the nanofiber membrane design and structure by manipulating material, process and surrounding parameters in the electrospinning process. This chapter highlights the recent advances and developments on the potential and application of electrospun nanofibers for water/ wastewater treatment. Comprehensive discussion is presented here on various designs and structures of nanofibers and their applications to water-related treatment and the future prospects of such materials.

“…Furthermore, the obvious peak at the binding energy of 284.7 eV was ascribed to the long carbon chain skeleton (CC) vibration of the PVA/PEI. The peak at 285.8 eV was attributed to the carbon and nitrogen single bond (CN) vibration of the PEI macromolecular chain . It was considered that carbon and oxygen single bond (COH) vibration of the PVA macromolecular chain resulted in formation of the characteristic peak at 286.7 eV.…”

A novel reversible photo‐responsive polyvinyl alcohol (PVA)/polyethylenimine (PEI) electrospinning nanofiber membrane (NFM), assembled with photochromic nanoparticles containing spiropyran, is herein presented and the water resistance, mechanical properties as well as photochromic properties are investigated systematically. Here, glutaraldehyde, which can undergo a cross‐linking reaction with PVA/PEI, is selected as a cross‐linker to enhance water resistance and mechanical behavior of the NFM. Photochromic polymer nanoparticles are prepared using octadecyl acrylate as polymer matrix monomer through miniemulsion polymerization. Effect factors of the whole preparation process such as the PVA/PEI mass ratio, the amount of emulsifier, and the amount of photochromic nanoparticles added are regulated to obtain the optimal experimental parameters. The surface morphology and microstructure, water resistance, and mechanical properties of NFMs are studied by thermal field emission scanning electron microscopy, static water contact angle tester, and tensile universal testing machine, respectively. Furthermore, UV–vis spectrophotometer is employed to investigate the photochromic performance and fatigue resistance of NFMs. Overall, analyses reveal that the reversible photo‐responsive electrospinning NFM exhibit excellent photoresponsivity, photoreversibility, and fatigue resistance upon UV irradiation, thus showing promising application in the field of ultraviolet intensity indicator.

“…The obtained EVOH−CCA membranes showed a high static adsorption capacity of 284 mg/g toward lysozyme at pH 6 thanks to a large amount of carboxyl groups of CCA on the nanofiber surface. Moreover, Zhu et al [21] functionalized the surface of electrospun PVA/PEI with a thin coating of polydopamine/polyethyleneimine (PDA/PEI). The obtained core-shell structured PDA/PEI@PVA/PEI adsorbed Ponceau S and Methylene Blue dyes with adsorption capacities of 1180 and 1290 mg/g, respectively.…”

The separation and purification of specific chemicals from a mixture have become necessities for many environments, including agriculture, food science, and pharmaceutical and biomedical industries. Electrospun nanofiber membranes are promising materials for the separation of various species such as particles, biomolecules, dyes, and metals from liquids because of the combined properties of a large specific surface, light weight, high porosity, good connectivity, and tunable wettability. This paper reviews the recent progress in the design and fabrication of electrospun nanofibers for chemical separation. Different capture mechanisms including electrostatic, affinity, covalent bonding, chelation, and magnetic adsorption are explained and their distinct characteristics are highlighted. Finally, the challenges and future aspects of nanofibers for membrane applications are discussed.
