“…For solution in 10% of acetic acid, the addition of PEO to Cs leads to a decrease in viscosity from 1.114 to 1.002 Pa s. On the opposite, PEO addition to solution in high acidity (50% and 90% of acetic acid) leads to an increase of the viscosity. The same result was reported in Kriegel et al (2009a) work on the addition of PEO to Cs solutions with 50% and 90% of acetic acid.…”

“…The voltage causes a jet of polymer solution to be expelled from the syringe and moved towards an appropriate collector plate. As the solvent in the jet dries, the remaining polymer solidifies and forms ultrafine nanofibers that are collected on the collector plate (Kriegel, Kit, McClements, & Weiss, 2009a).…”

“…To facilitate Cs electrospinning, it was necessary to blend or crosslink it using other polymers such as PEO (Du & Hsieh, 2007;Kriegel et al, 2009a) or poly(vinyl alcohol) (PVA) (Li & Hsieh, 2006;Shan, Zhi, & Jun, 2007). Electrospinning of Cs has been investigated by various authors all of which conclude that the production of pure Cs nanofibers was very challenging (Duan, Dong, Yuan, & Yao, 2004;Huang, Ge, & Xu, 2007;Li & Hsieh, 2006).…”

“…Surfactants are amphiphilic molecules that readily absorb at surfaces and thereby lower the interfacial tension; a key parameter that influences electrospinning. Bhattarai et al (2005) studied the use of Triton X-100 and Kriegel et al (2009a) evaluated the effect of anionic sodium dodecyl sulfate (SDS), nonionic polyoxyethylene glycol lauryl ether (Brij 35), and cationic dodecyltrimethylammonium bromide (DTAB). It has been reported that the addition of a small amount of nonionic surfactant to polymer solutions reduced the onset voltage required to induce spinnability and improved reproducibility of the electrospinning process (Yao et al, 2003).…”

a b s t r a c tBlend solutions of chitosan (Cs) and poly(ethylene oxide) (PEO) at different acidities were electrospun to produce membranes of nanofibers with different diameters. The use of polysorbate surfactant Tween 20 to improve functionality of these nanofibers was studied. The procedure was as follows: 5% (w/v) of two high deacetylation degree Cs with different molecular weights (Mw = 148 kDa and 68 kDa) were dissolved in solutions with different acetic acid concentrations (10%, 50% and 90% (v/v)) then mixed with PEO. The influence of molecular weight and acidity on the morphology and physicochemical properties of solutions and formed nanofibers was also investigated. Results revealed that pure Cs dissolved in different acidities did not form fibers and instead it deposited as beads. Addition of PEO was necessary to electrospin all Cs solutions. Average fiber diameters and size distribution differ with acidity and molecular weight. Composite solutions of Cs, synthetic polymer PEO, and surfactant can be effectively electrospun. The presence of surfactant resulted in decrease of surface tension and in the formation of smooth or beaded fibers. This may be important for new applications since active nanofibers could serve as carriers of components such as drugs or additives.
