Electrospinning of food-grade nanofibers from cellulose acetate and egg albumen blends

Effects of poly(ethylene oxide) and ZnO nanoparticles on the morphology, tensile and thermal properties of cellulose acetate nanocomposite fibrous film

“…This phenomenon was also observed during our previous study. 9 However, the range of PEO blending ratios used in this study did not yield differences in the blend's fiber diameters (PX0.05). Even though the viscosity of these blends was significantly reduced, the diameters of the resulting fibers were not affected because the lower viscosity influence was balanced by the lower surface tension and higher electrical conductivity of the blend solution.…”

“…Preliminary study of polymer solution concentrations of CA and PEO Han et al 18 reported that CA electrospun fibers could be fabricated from a 17% (w/v) of CA in 75% acetic acid, whereas Wongsasulak et al 9 reported that the same could be prepared using a solution of 17% (w/v) CA in 85% acetic acid. The effects of both solvents as well as that of neat acetic acid (99.99%) were investigated, as shown in Figures 1a-c. CA in 75% (Figure 1a) and 85% (Figure 1b) (v/v) acetic acid solutions resulted in beaded fibers with diameters on the nanometer-length scale.…”

“…These results suggested that the fine morphology of the electrospun fibers can be successfully created by the proper modulation of the solution properties; similar results have also been reported by other researchers. 9,17,[19][20][21][22][23][24][25] The Fourier-transform infrared spectra of the electrospun CA fibers showed a strong ester carbonyl stretching vibration at 1750 cm À1 , 26 whereas those of PEO fibers exhibited strong peaks at 2900 cm À1 that were attributed to the molecular stretching of methylene groups (CH 2 ). 9 The Fourier-transform infrared spectra of the CA-PEO fibers exhibited both of these characteristic peaks, as shown in Figure 4.…”

“…The inclusion of organic and inorganic additives represents an effective route to the physical and mechanical modification of CA-based materials. [8][9][10][11][12][13] Long linear chain molecular polymers, such as poly (ethylene oxide) (PEO), are expected to impart high flexibility to the CA matrix. PEO is one of the most biocompatible synthetic polymers; it is approved by the Food and Drug Administration for safe use in foods and pharmaceuticals.…”

Characteristics of vitamin E-loaded nanofibres from dextran

“…The applied voltage should be sufficient to overcome the surface tension at the tip of the Taylor cone, in order to initiate the ejection of the charged jet. [26] Using of higher voltage to a certain point, initially leads to the formation of fibres of smaller diameter, then thicker fibres are formed. Thus there is an ideal applied voltage that results in a minimum fibre diameter depending on the polymer and interacting parameters.…”
