Abstract:
Michael addition reaction of Chitosan (CS) and polyethylene glycol diacrylate (PEGDA) was carried out successfully in acidic solution. Films with CS/PEGDA weight ratios from 100/0 to 0/100 in 10% increments were analyzed by Fourier transform infrared (FTIR) spectroscopy, Scanning Electron Microscope (SEM) and X-Ray Diffraction (XRD). Additionally, the films were characterized by measuring mechanical property, swelling property. The potential application of the CS/PEGDA film as wound dressing material was evaluated in vitro by using mouse fibroblasts (L929) as reference cell lines, indirect cytotoxicity assessment indicated that CS/PEGDA films were nontoxic to L929 cell.
