Tóm tắt

An integrated strategy that combines innovative electrospinning technique with traditional hot-stretching post-treatment is designed and implemented to generate high-molecular-weight poly(l-lactic-acid) (hmwPLLA, Mw = 2 80 000 Da) electrospun nanofiber-constructed yarns (ENCYs). The internal fiber diameter within the hmwPLLA ENCYs is found to increase gradually with the increase of hmwPLLA solution concentration. The hmwPLLA ENCY generated from a concentration of 10% (w v
