“…However, this rearrangement of molecules is dependent on the position in the electrospinning process thereby eventually giving rise to instabilities. This agrees with the reported instabilities observed in literature while electrospinning polyamide 6.6 in pure formic acid [23]. On the other hand the conductivity of a polymer solution composed of pure acetic acid is too low which also results in unstable electrospinning [24].…”

“…These are nevertheless essential for a potential breakthrough of the system. Steady state electrospinning is reported for other polymers as a solution for obtaining a high stability and reproducibility [23,24]. This steady state implies a continuously 3 stable Taylor cone as a function of time together with an equal amount of polymer that is transported through the needle per time unit to the amount that is deposited as fibres on the collector plate per time unit [23].…”

The steady state condition requires stability of the process in time and is thus more strict than the common conditions for stable electrospinning described in literature so far [4,[25][26][27][28].…”

Polycaprolactone (PCL) is a biocompatible aliphatic polyester with many possible applications in the medical field. PCL nanofibres, produced by electrospinning, could provide new characteristics that are of interest for these applications. However, a key prerequisite is the ability to obtain bead-free fibres with diameters in the nanoscale range. At present the most commonly used solvent for electrospinning PCL is chloroform, but this only leads to fibres in the microscale range. Therefore various solvent systems were examined in this study.The innovative solvent mixture formic acid/acetic acid was found to allow for nanofibres with a diameter ten times smaller than chloroform. Moreover, steady state conditions could be obtained which thus allow electrospinning in a stable and reproducible way. Further it was noticed that the average fibre diameter decreased with decreasing polymer concentration while the diameter distribution decreased with increasing amount of formic acid. Also the humidity, an often overlooked yet important parameter, was noted to affect both diameter 2 characteristics. Generally it can be concluded that the solvent system formic acid/acetic acid could fill the gap in electrospinning PCL since it is readily able to produce uniform fibres in the nanoscale range.

“…This high surface to volume ratio nanofibers was achieved with the use of a new solvent system that involves an acid base reaction to produce weak complexes which serves to increase the conductivity of the polymer solution. Additionally, the weak complex formed dissociates easily and evaporates along with the solvent during the electrospinning process [104].…”

Abstract:Electrospinning is a highly versatile technique to prepare continuous fibers with diameters of the order of nanometers. The remarkable high aspect ratio and high porosity bring electrospun nanofibers highly attractive to various nanotechnological applications such as filtration membranes, protective clothing, drug delivery, tissue-engineering, biosensors, catalysis, fuel cells and so on. In this review, we collectively summarized the recent progress in developments of the electrospun ultrafine polyamide-6 based nanofibers preparation, characterization and their applications. Information of this polyamide-6 and composites together with their processing conditions for electrospinning of ultrafine nanofibers has been summarized in this review. The recent developments made during last few years on these materials are addressed in this review. We are anticipating that this review certainly drive the researchers for developing more intensive investigation for exploring in many technological areas.

“…Electrospinning has been used since the early 1930s, and offers a non-woven, three-dimensional, porous, and nanoscale, fiber-based matrix. [14][15][16] It creates ultrafine fibers by electrically charging a suspended droplet of melted polymer or polymer solution, and PLGA fibrous scaffolds created through electrospinning are similar to the natural extracellular matrix (ECM). 17,18 Limitations to PLGA include a lack of hydrophilicity, bioactivity, [19][20][21] and a compromised mechanical strength.…”

A mesoporous bioactive glass (MBG) surface modified with poly(lactic-co-glycolic acid) (PLGA) electrospun fibrous scaffold for bone regeneration was prepared by dip-coating a PLGA electrospun fibrous scaffold into MBG precursor solution. Different surface structures and properties were acquired by different coating times. Surface morphology, chemical composition, microstructure, pore size distribution, and hydrophilicity of the PLGA-MBG scaffold were characterized. Results of scanning electron microscopy indicated that MBG surface coating made the scaffold rougher with the increase of MBG content. Scaffolds after MBG modification possessed mesoporous architecture on the surface. The measurements of the water contact angles suggested that the incorporation of MBG into the PLGA scaffold improved the surface hydrophilicity. An energy dispersive spectrometer evidenced that calcium-deficient carbonated hydroxyapatite formed on the PLGA-MBG scaffolds after a 7-day immersion in simulated body fluid. In vitro studies showed that the incorporation of MBG favored cell proliferation and osteogenic differentiation of human mesenchymal stem cells on the PLGA scaffolds. Moreover, the MBG surface-modified PLGA (PLGA-MBG) scaffolds were shown to be capable of providing the improved adsorption/release behaviors of bone morphogenetic protein-2 (BMP-2). It is very significant that PLGA-MBG scaffolds could be effective for BMP-2 delivery and bone regeneration.
