Abstract EN
Polycaprolactone nanofibers were prepared using five different solvents (glacial acetic acid, 90% acetic acid, methylene chloride/DMF 4/1, glacial formic acid, and formic acid/acetone 4/1) by electrospinning process.
The effect of solution concentrations (5%, 10%, 15% and 20%) and applied voltages during spinning (10 KV to 20 KV) on the nanofibers formation, morphology, and structure were investigated.
SEM micrographs showed successful production of PCL nanofibers with different solvents.
With increasing the polymer concentration, the average diameter of nanofibers increases.
In glacial acetic acid solvent, above 15% concentration bimodal web without beads was obtained.
In MC/DMF beads was observed only at 5% solution concentration.
However, in glacial formic acid a uniform web without beads were obtained above 10% and the nanofibers were brittle.
In formic acid/acetone solution the PCL web formed showed lots of beads along with fine fibers.
Increasing applied voltage resulted in fibers with larger diameter.
