“…Currently, a conventional solution electrospinning system consists of a high voltage power supply, one or more grounded collectors and a spinneret [207,208,213,214,215,216]. As shown in Figure 8, an electrospinning apparatus can be run vertically and horizontally at room temperature [207].…”

“…For PS membranes, some typical solvents have been used due to good volatility, vapor pressure and boiling point [207]. Typical examples are DMAC, DMF and acetone [207,208,209,213,214,215,216,218]. Moreover, as the solvent itself can interact with the electric field during the fiber formation, appropriate solvent polarity is important for fiber formation.…”

“…Meanwhile, the fiber diameter increased with increasing PS concentration as clearly illustrated in Table 8. Several studies found that the average fiber diameter increased with polymer concentration following a power-law with an exponent in the 2–3 range [209,213,214,221,222].…”

Porous polymeric membranes have emerged as the core technology in the field of separation. But some challenges remain for several methods used for membrane fabrication, suggesting the need for a critical review of the literature. We present here an overview on porous polymeric membrane preparation and characterization for two commonly used polymers: polysulfone and poly (vinylidene fluoride). Five different methods for membrane fabrication are introduced: non-solvent induced phase separation, vapor-induced phase separation, electrospinning, track etching and sintering. The key factors of each method are discussed, including the solvent and non-solvent system type and composition, the polymer solution composition and concentration, the processing parameters, and the ambient conditions. To evaluate these methods, a brief description on membrane characterization is given related to morphology and performance. One objective of this review is to present the basics for selecting an appropriate method and membrane fabrication systems with appropriate processing conditions to produce membranes with the desired morphology, performance and stability, as well as to select the best methods to determine these properties.

“…Aydemir Sezer et al [ 58 ] presented the sulfonation treatment of PSF that could replace the heparin-based functionalization of PSF via the introduction of the sulfonic acid group, SO 3 H, into the structure of a molecule using a chlorosulfonic agent as a sulfonating agent. A core—shell electrospun structure based on PSF core and sulfonated PSF shell was investigated.…”

“…The sulfonation treatment of PSF leads to an increase of the hydrophilicity of PSF indicating the improvement of blood compatibility due to hydrophilic groups on the surface of sulfonated PSF. The mechanical properties, hemocompatibility and biocompatibility properties of sulfonated PSF are improved in comparison with those of neat PSF [ 58 ]. In this study, Mahlicli et Altinkaya [ 59 ] modified PSF with alpha-lipoid acid (ALA), which is an antioxidant obtained from the reduced form of dihydrolipoic acid (DHLA), in order to obtain a hemodialysis membrane.…”

The field of membrane materials is one of the most dynamic due to the continuously changing requirements regarding the selectivity and the upgradation of the materials developed with the constantly changing needs. Two membrane processes are essential at present, not for development, but for everyday life—desalination and hemodialysis. Hemodialysis has preserved life and increased life expectancy over the past 60–70 years for tens of millions of people with chronic kidney dysfunction. In addition to the challenges related to the efficiency and separative properties of the membranes, the biggest challenge remained and still remains the assurance of hemocompatibility—not affecting the blood during its recirculation outside the body for 4 h once every two days. This review presents the latest research carried out in the field of functionalization of polysulfone membranes (the most used polymer in the preparation of membranes for hemodialysis) with the purpose of increasing the hemocompatibility and efficiency of the separation process itself with a decreasing impact on the body.

Electrospinning, a common method for synthesizing 1D nanostructures, has contributed to developments in the electrical, electrochemical, biomedical, and environmental fields. Recently, a coaxial electrospinning process has been used to fabricate new nanostructures with advanced performance, but intricate and delicate process conditions hinder reproducibility and mass production. Herein, recent progress in new emerging parameters for successful coaxial electrospinning, and the various nanostructures and critical application areas resulting from these activities. Relationships between the new parameters and final product characteristics are described, new possibilities for nanostructures achievable via coaxial electrospinning are identified, and new research directions with a view to future applications are suggested.
