Preparation and Characterization of KGM/PVA Composite Nanofibrous Membranes

Article Preview

Abstract:

A composite membrane of KGM/PVA was prepared by electrospinning process. KGM and PVA were dissolved in water and acetic acid (volum:6/4) with different concentration and the resulting blend sol was electrospun into the composite nanofibrous membranes. The influence of technical parameters on morphology and diameter of nanofibers was investigated by Scanning Electron Microscope (SEM). The results show that the concentration of KGM/PVA blend sol affects significantly on the fiber diameter and the morphology of composite membranes, and the increase of the voltage results in the decrease of the fiber diameter. The composite nanofibrous membranes with the average fiber diameter ranging from 87.5nm to 165.6nm were fabricated by electrospinning at the following conditions: 10% (w/v) of the concentration of KGM/PVA blend sol (weight ratio of KGM to PVA=4/6), 25KV of electric voltage, 0.0025mm s-1 of the feeding rate, 45°C of the electrospinning temperature and 16cm of receiving distance.
