“…Nanofiber composites and membranes have increased in practical applications due to the widespread use of sub-micron to nano-scale fibers [1]. Electrospinning is more commonly used to fabricate micro and nanofibers compared with other conventional processes, such as phase separation, interfacial polymerization, self-assembly, wet spinning, and drawing [2][3][4][5][6][7]. These fibers have many applications, such as reinforcement phase in composites, personal protective textiles, filtration, biomedical devices, electrical and optical devices, nano-sensors, etc.…”

A series of electrospun polyvinyl alcohol (PVA) fiber membranes were crosslinked with citric acid (CA) at concentrations of 10, 20, and 30 wt.% (designated as CA10, CA20, and CA30). The effects of CA on the chemical structure, mechanical strength, swelling resistance, and cytotoxicity of the crosslinked PVA fibrous membranes were investigated. Infrared spectroscopy indicated the enhanced esterification of carboxyl and hydroxyl groups between CA and PVA. The modulus and strength of the electrospun PVA membrane increased due to the crosslinking between CA and PVA. The crosslinking of the PVA fiber matrix with CA increased the PVA binding point, thereby increasing the swelling resistance and modulus; however, the concentration of CA used was limited. Results showed that the water absorption of the PVA membranes decreased from 6.58 ± 0.04 g/g for CA10 to 3.56 ± 3.33 g/g for CA20 and 2.85 ± 0.40 g/g for CA30 with increasing CA. The water absorption remained unchanged after the membrane was soaked for a period of time, so no significant difference was found in the water absorption capacity of the same group after immersion from 1 h to 3 d. The tensile strength increased from 20.52 MPa of CA10 to 22.09 MPa of CA20. With an increased amount of CA used for crosslinking, the tensile strength and modulus of CA30 decreased to 11.48 and 13.94 MPa, respectively. Our study also showed that CA was not toxic to L929 cell viability when used for fiber crosslinking at less than 20 wt.% PVA, meaning it may be a good candidate as a support layer for guided tissue engineering.

“…Because fibers with nanometric scale demonstrate high efficiency in wastewater treatments, we focus on their properties and structures. These types of materials can be obtained using a variety of techniques, as described by Ahmed and colleagues [40] in their review, including self-assembly and electrospinning as emerging techniques [116][117][118], drawing [119][120][121][122], template synthesis [103,[123][124][125], and phase separation [126][127][128]. The type of polymer controls the morphology, shape, size, and strength of the nanofibers.…”

Multifunctional Membranes—A Versatile Approach for Emerging Pollutants Removal

et al. 2022

View full text Add to dashboard Cite

This paper presents a comprehensive literature review surveying the most important polymer materials used for electrospinning processes and applied as membranes for the removal of emerging pollutants. Two types of processes integrate these membrane types: separation processes, where electrospun polymers act as a support for thin film composites (TFC), and adsorption as single or coupled processes (photo-catalysis, advanced oxidation, electrochemical), where a functionalization step is essential for the electrospun polymer to improve its properties. Emerging pollutants (EPs) released in the environment can be efficiently removed from water systems using electrospun membranes. The relevant results regarding removal efficiency, adsorption capacity, and the size and porosity of the membranes and fibers used for different EPs are described in detail.
