Poly (lactic) acid (PLA)/poly (caprolactone) (PCL) blends nanofibers, with mean diameter about 600nm, were prepared by electrospinning. This research focused on the morphological and thermal properties of nanofibers made from PLA/PCL bends with different PCL content. The results showed that the addition of PCL could improve the morphology of the nanofibers. The film with blend fiber at PLA/PCL ratio of 80: 20 is characterized with the smoothest surface and the highest orientation. The diameter distribution of blend fibers is wider than that of pure PLA. The glass-transition temperature of PLA for blend fiber is higher than that of pure PLA, and their melting temperature is lower than that of pure PLA. It can be used in biomedical field for degradable membrane, anti-adhesive film and medical equipment.
