摘要
Chitosan was grafted with a novel monomer 1-Cyanoethanoyl-4-acryloylthiosemicabazide (CEATS). The graft copolymerization was conducted using potassium persulfate (K2S2O8) and sodium bisulfite (NaHSO3) as redox initiators. The grafted samples were characterized by FTIR spectroscopy, scanning electron microscopy, X-ray diffraction, and thermogravimetric analysis. The data may indicate that grafting has occurred at the surface of chitosan. The grafted samples showed high water swelling. The antifungal behavior of chitosan and its graft copolymers was investigated in vitro and it has been found that grafting with CEATS noticeably enhances the antifungal activity.
