The Effect of Humidity on the Morphological Evolution of β-Chitin Prepared by Electrospinning

Abstract

The β-chitin nanofiber composite was prepared by the electrospinning method. When β-chitin and its compounds are blended with polyethylene oxide (PEO), the electrospinning performance is significantly improved. The fiber diameter of the mixed β-chitin/PEO nanofiber is about 355nm, but with the longer storage time in a high humidity environment, the fiber diameter will increase to 3.75μm after 7 days, and the melting temperature (Tm) will be 12 oC higher than that of the initial spinning.
