“…This was due to the polar molecules being inserted between the molecules of cysteine, and resulted in an increase in their molecule distances. The strength of the film was affected by the breakage of the disulfide or H-bond 17 . The keratin blended films varied in color and transparency as well as texture depending on the added molecules and ratio used.…”

Keratin solution was separately blended with collagen, gelatin, sericin and starch for films preparation. All the blended films had smooth surfaces without phase separation, except the keratin/ starch blend film. The native keratin film showed small particles embedded in all the film surfaces that resulted in them being rough. The structure of the native keratin film changed from beta-sheet to random coil at high blend ratio of other substances. This result increased the dissolution of the films especially the keratin/starch blend. The results relate directly to the decreased thermal stability of this film. However, the changes in structure did not affect the chlorhexidine release pattern. It is possible that the interaction between the drug and blending substances, and the substances to water molecules are the main factor influencing the drug release pattern from the films.

“…For instance as the concentration, or similarly, the viscosity increases, higher electrical forces are required to overcome both the surface tension and the viscoelastic forces for fibre stretching. The size of the droplet at tip of the nozzle depends on the feeding rate as well as the needle shape and diameter [13,[62][63][64]. Therefore, these factors influence the forces acting on the drop which contribute to the jet initiation and stretching.…”

Abstract. Over the past decades, electrospinning of biopolymers down to nanoscale garnered much interest to address most of the millennia issues related to water treatment. The fabrication of these nanostructured membranes added a new dimension to the current nanotechnologies where a wide range of materials can be processed to their nanosize. Electrospinning is a simple and versatile technique to fabricate unique nanostructured membranes with fascinating properties for a wide spectrum of applications such as filtration and others. These nanostructured membranes, fabricated by electrospinning, were found to be of a paramount importance because of their advanced inherited properties such as large surface-to-volume ratio, as well as tuneable porosity, stability, and high permeability. The extensive research conducted on these materials extended the success of electrospinning not only to bio-based polymer nanofibres, but to their hybrids and their derivatives. The technique also created avenues for advanced and massive production of nanofibres. This paper reviews the recent developments in the electrospinning technique. Electrospinning of biopolymers, their blends and functionalization using metals/metal oxides, and the potential applications of electrospun nanofibrous membranes in water filtration are discussed.

T HE MAJOR challenge of the electrospinning process lies in the optimization of its parameters to achieve desirable nanofibers morphology and properties. The present work highlights the change of properties for electrospun poly ɛ-caprolactone and poly ethylene oxide with modulation of different parameters. The effect of solution parameters such as; concentration poly ɛ-caprolactone, concentration of poly ethylene oxide relative to poly ɛ-caprolactone, viscosity , different solvents, voltage properties and distance separates tip of the syringe and collector to fabricate poly ɛ-caprolactone electrospun nanofibers with desired morphologies is indicated in present work. Morphologies of the processed nanofibers are examined by FESEM, the average diameter of nanofibers and their normal distribution are investigated by image j analyzer software. Of all combinations, the best and the finest nanofibers are obtained at 10%w/v poly ɛ-caprolactone, 3% w/v poly ethylene oxide concentration with respect to that of poly ɛ-caprolactone, at voltage 20 kV and lastly at 12 cm distance separate the tip of syringe and collector. Controlling the features of electrospun fibers via variation on the operating parameters, allow applications of fibers on different fields.
