  Abstract

Post-crosslinking treatment is essential for improving the water tolerance of the electrospinning keratin/Poly(ethylene oxide) (PEO) nanofiber membrane to meet the requirement of the biomedical application. In this study, three ecofriendly low-cost methods, hot air, pure oxygen, and ultraviolet irradiation were employed as the post-crosslinking treatment to prepare the electrospun keratin/PEO (90/10) nanofiber membrane with good water tolerant. A comparative study between the performances of the nanofiber prepared by different cross-linking methods were carried out. The results showed the three postcrosslinking methods were all effective for transforming the water-soluble keratin/PEO nanofiber membranes to the water insoluble membranes. However, the mechanical property, water sorption and swelling rate, molecular structure, thermal property, and crystallinity of the nanofiber membranes were all different due to the different post-crosslinking methods. After heat treatment, the tensile strength of the nanofiber membrane can reach 2.29 MPa, while that of the oxygen crosslinking and ultraviolet crosslinking are 0.99 and 1.68 MPa, respectively. The water absorption and swelling of the oxygen and ultraviolet crosslinking membranes are relatively large, and the swelling rate is about 21%. The oxygen crosslinking membrane possessed higher hydrophilicity and the contact angle is only 21
