Electrospinning Fabrication of Chitosan/Polyvinyl Alcohol Nanofibers: Surface Morphology and Optical Properties Investigation"

Abstract

In this study nanofiber PVA/Chitosan with volume ratio 7:3(V/V) have been prepared by electrospinning method. Electrospinning was performed at a voltage 18 kV, with a tip-collector distance of 10 cm and flow rate 1ml/h. The structure of PVA/Chitosan was examined by FTIR, XRD and SEM, Tensile strength and contact angle (CA) were also investigated. The results showed that PVA/Chitosan nanofiber was successfully formed with small beads with smooth surface. SEM observation showed that the fiber had several hundred nanometers about 230nm.
