Wool keratin/poly(vinyl alcohol) (PVA) blend nanofiberswere fabricated using the electrospinningmethod in formic acid solutions\r\nwith different weight ratios of keratin to PVA.The resultant blend nanofibers were characterized by scanning electron microscopy\r\n(SEM), Fourier transform infrared (FTIR), X-ray diffraction (XRD), thermal gravimetric analysis (TGA), and tensile test. SEM\r\nimages showed that the diameter of the blend nanofibers was affected by the content of keratin in blend solution. FTIR and XRD\r\nanalyses data demonstrated that therewere good interactions between keratin and PVAin the blended nanofibers caused by possibly\r\nhydrogen bonds. The TGA study revealed that the thermal stability of the blend nanofibers was between those of keratin and PVA.\r\nTensile test indicated that the addition of PVA was able to improve the mechanical properties of the electrospun nanofibers.
