Tailoring crystallinity of electrospun Plla fibres by control of electrospinning parameters [PDF]

, 2012
Poly(L-lactic acid) (PLLA) fibers were fabricated by electrospinning. The effects of various electrospinning process parameters on the thermal properties, especially the crystallinity of the electrospun fibers were investigated.
