Abstract

Feather keratin (FK)/PVA composite nanofibrous membranes were prepared through an electrospinning process, using water as solvent. The interaction and compatibility between FK and PVA, as well as the effect of incorporating FK on the morphology, crystallinity, thermal stability and hydrophilicity of the composite nanofibrous membranes were evaluated. At a total polymer concentration of 14%, the prepared nanofibers were smooth, bead-free and the average diameter was in the range of 250—320 nm. The more FK was added, the lower fiber diameter was obtained. The favorable compatibility and strong interactions between FK and PVA were confirmed by FTIR analysis. XRD analysis indicated that the arrangement of PVA chain in the composite nanofibrous membranes was disturbed by the incorporation of FK, resulting the decrease of crystallinity. According to TG and contact angle analysis, the thermal stability and hydrophilicity of the composite nanofibers were both enhanced by increasing the FK content.
