Abstract: The present work focuses on the fabrication and crosslinking modification of a feather keratin/poly(vinyl alcohol)/poly(ethylene oxide) ternary hybrid nanofibrous membrane. We mixed chicken feathers keratin (FK) (pre-extracted from chicken feathers by oxidation method), poly(vinyl alcohol) (PVA) and poly(ethylene oxide) (PEO) to prepare the spinning solution, and then fabricated the FK/PVA/PEO nanofibrous membrane through a electrospinning process. The glyoxal which acted as a crosslin-king agent was also added into the spinning solution in order to improve product’s performance. The fabricated (crosslinking-modified and unmodified) membranes were characterized by using a scanning electron microscope (SEM), a Fourier transform infrared (FT-IR) spectroscope, an X-ray diffractometer (XRD), a thermogravimetric analyzer (TGA), a water contact angle tester and a universal testing machine. The results indicated an increase of average fiber diameter from (249.76±38.02) nm to (399.67±53.44) nm and a contact angle rise from (42.1±5.1) ° to (84.9±7.1) °, whilst the glyoxal/FK mass ratio was raised from 0% to 8%. The hybrid membranes with 6% glyoxal/FK mass ratio showed pleasurable mechanical properties, as the tensile strength and Young’s modulus reached 4.57 MPa and 6.64 MPa, respectively.
