Fabrication of Poly(Caprolactone) Nanofibers by Electrospinning

Abstract

Nanofibers at 466 ± 242 nm average diameter were fabricated due to phase separation caused by polarizability difference under static electric field. Fibre morphology was observed under a scanning electron microscopy. An insight into the process of electrospinning of the polymer, poly(caprolactone) was systematically evaluated and discussed the effects of the solution parameter of concentration of the polymer solution and process parameters of voltage, flow rate and drop height to fabricate poly(caprolactone) electrospun fibers with desired morphologies in this manuscript. Of all combinations, the best nanofibres with the fewest beads and finest fibers could be electrospun with a more uniform distribution in with a 15 kV applied voltage of on poly(caprolactone) solution of 12 per cent concentration at a 0.5 ml/h flow rate, from a drop height of 15 cm and the structure of nanofibres was found completely dry and stabilized.
