- Abstract:
- In this study,polylactic acid ( PLA )-polycaprolactone ( PCL) composite fiber with core-shell struc-ture was fabricated by means of co-axial electrospinning. SEM was employed to study the impacts of electro-spinning voltage,collected distance and ratio of core-shell solution injection speed on morphology of PLA-PCI.composite fiber with core-shell structure. The influences on the formation of the core-shell structure under dif-ferent ratio of core-shell solution injection speed were observed with TEM. The results showed that the obviouscore-shell structure was fabricated when core-shell solution injection speed was 0. 1-0.2 and 0.1-0.3 mL/h.The core component in PLA-PCL composite fiber decreases with the increase of shell solution injection speed.The increasing of electrospinning voltage could efficiently reduce the average diameter of composite fiber. Theaverage diameter of composite nanofiber decreases and then increases with the increase of collection distance.
