In this study, modified coaxial electrospinning (CE) was employed to improve electrospinnability and to tailor surface morphology and bead formation of poly(lactic acid) (PLA) fibers by means of core-to-shell flowrate ratio variation. Chloroform/N,N-dimethylformamide (DMF) mixture was used as sheath...
