“…It has been determined by other research groups that high molecular weight PEO facilitates the electrospinning process because of its unique viscoelastic properties . Several research groups investigated the electrospinning of lignin . These studies demonstrated that the addition of PEO to lignin suspension aids the production of good quality fibers during the electrospinning process …”

The effects of polyethylene oxide (PEO) molecular weight (Mv), and volume fraction ( ϕ) on the morphology of electrospun sulfur free softwood lignin nanofibers were investigated. Small amounts of PEO were used during preparations of the solutions to aid the electrospinning process. It was found that tripling the PEO volume fraction resulted in a transition from semi‐dilute un‐entangled to semi‐dilute entangled solutions. Conversely, the solution remained in the semi‐dilute un‐entangled regime as the molecular weight was increased by five times. The effects of molecular weight and volume fraction of PEO both on entanglement density and fiber morphology were unified by scaling PEO viscosities as a function of ϕ1.3Mvpolymer. We investigated and discussed conditions that would produce smooth fibers and conditions that would produce fibers with beads. In the case of beads‐on‐a‐string formation, bead widths remained constant regardless of the molecular weight and concentration of PEO, but the bead length changed. Additionally, we observed a decrease in the diameter of the fibers and the dimension of beads (length and width of beads) with an increase in the electric field used for electrospinning. The aspect ratio of beads increased with increases to both the electric field and the PEO molecular weight or concentration. © 2016 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2016, 133, 44172.

“…Hence, a 70:30 Na-alginate/PEO of 4 wt% solution is used for electrospinning experiments. Numerous studies (Baumgarten 1971 Poursorkhabi et al 2015) were carried out to investigate the effect of storage time (ageing) of spinning solution on fibre diameter and morphology. This study focuses the effects of ageing of spinning solution of Na-alginate/PEO on viscosity, fibre diameter and morphology.…”

Poly(ethylene oxide) (PEO) loaded alginate nano-fibres were produced by electrospinning of the 4 % (w/w) of 70:30 Na-alginate/PEO spinning solution. In this research, the effects of solution viscosity and storage time of the spinning solution on fibre diameter and morphology were studied. Results show that the viscosity of the spinning solution was 2284 cP at the age of day 1, which was dropped slowly and reached at 2184 cP until day 5. However, the viscosity sharply decreased after 5 days of storing and the mean diameter of the fibres remain similar until 20 days though the uniformity of the fibre diameters decreased significantly. At day 40, the viscosity of the spinning solution dropped 48 cP which yields beads-onstring fibres. The solutions of 5 days and 10 days old produced smooth and uniform nanofibres having mean diameter of 133 nm and 132 nm, respectively. They also produced stable electrospinning fibre jet compared to other solutions. Overall, the results revel that the electrospinnability of Naalginate/PEO spinning solution remain suitable until 10 days of storing time.

“…Various types of polymers have been used in fiber production using electrospinning technology, including natural polymers such as silk fibroin (Min et al 2004), gelatin (Zhang et al 2005), chitosan (Ohkawa et al 2004), lignin (Dallmeyer et al 2010;Ago et al 2012;Teng et al 2013;Salas et al 2014;Poursorkhabi et al 2015), cellulose (Kim et al 2006;Han et al 2008), and hemicellulose (Gan et al 2013). Dallmeyer et al (2010) used seven different types of technical lignin in electrospinning to produce micro-to submicroscale fibers.…”

Lignosulfonate fibers were produced using electrospinning technology, a method of manufacturing fibrous materials using polymeric solutions, by adding traces of polyethylene oxide to lignosulfonate solutions. Continuous and uniform fibers were obtained under appropriate processing conditions. Solution concentration, applied voltage, flow rate, and syringe-to-collector distance all had effects on fiber formation and diameter. Certain interactive effects among these processing parameters were also observed. Solution concentration was the most significant parameter influencing the diameters of the resulting lignosulfonate fibers. Higher solution concentrations resulted in greater fiber diameters. A broader distribution of fibers was observed as the solution concentration increased. Applied voltage, flow rate, and syringe-to-collector distance had moderate effects on the fiber diameters, and needle gauge had a minor impact on the fiber diameters.
