Preparation of a Novel Chitosan-based Composite Nanofibers by Electrospinning

摘要

A novel chitosan-based composite nanofibers which was composited poly (vinylpyrrolidone) (PVP) and poly (vinylalcohol) (PVA)was prepared by electrospinning, and the spinnability and morphology of CS-based composite nanofibers were investigated. The result of SEM showed that with the introduction of PVP to composite fibers the spinnability of the system was improved. And the CS/PVA/PVP composite fibers displayed mean diameter of 71 nm and narrower diameter distribution than CS/PVA composite fibers. IR demonstrated that there were intermolecular hydrogen bonds in CS/PVA/PVP fibers. XRD showed that the crystalline microstructure of the fibers was not well developed.
