Abstract

The Polyvinylpyrrolidone (PVP) / Poly (L-lactic acid) (PLLA) ultrafine blend fibers have been prepared for the first time by electrospinning. Trichloromethane was found to be the co-solvent for electrospinning. The PVP/PLLA blend solutions in various ratios were studied for electrospinning into ultrafine fibers. The morphology of the fibers was shown by scanning electron microscope (SEM). It was found that the morphology of the fibers became finer with the content of PLLA increasing. To show the molecular interactions, PVP/PLLA fibers were characterized by Fourier transform infrared spectroscopy (FTIR). The spun ultrafine fibers are expected to be used in the native extracellular matrix for tissue engineering.
