Abstract

The 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 separates the tip of syringe and collector.
