Fabrication and characterization of poly (vinyl alcohol)/chitosan blend nanofibers produced by electrospinning method

A series of poly (vinyl alcohol) (PVA)/chitosan (CS) blend nanofibrous membranes with different weight ratio of PVA to CS were fabricated by electrospinning method. The morphology, diameter, and structure of electrospun nanofibers were investigated by scanning electron microscopy (SEM), fourier transform infrared (FT-IR), X-ray diffraction (XRD) and differential scanning calorimetry (DSC). SEM images showed that the morphology and diameter of...
