摘　　要：Crosslinked chitosan-based nanofibers were successfully prepared via clectrospinning technique with heat mediated chemical crosslinldng followed. The structure, morphology and mechanical property of nanofibers were characterized by attenuated total reflection-Fourier transform infrared spectroscopy （ATR-FTIR）, scanning electron microscopy （SEM）, Instron rnachine, respectively. The results showed that, nanofibers exhibited a smooth surface and regular morphology, and tensile strength of nanofibers improved with increasing of triethylene glycol dimethacrylate （TEGDMA） content.Crosslinked chitosan-based nanofibers were successfully prepared via clectrospinning technique with heat mediated chemical crosslinldng followed.
