Preparation and Characterization of Konjac/Gelatin Composite Nanofibrous Membranes

Abstract:

A composite membrane of konjac/gelatin was prepared by electrospinning process. Gelatin and konjac were dissolved in acetic acid 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 gelatin/konjac 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 356nm to 463nm were fabricated by electrospinning at the following conditions: 25% (w/v) of the concentration of gelatin/konjac blend sol (weight ratio of gelatin to konjac=125/1), 20KV of electric voltage, 0.0025mm s-1 of the feeding rate, 42°C of the electrospinning temperature and 15cm of receiving distance.
