Abstract:The CTS-PVP film with iodine was prepared by chitosan(CTS) grafted polyvinyl pyrrolidone(PVP) in the protection of N2 with dimethyl 2, 2'-azobis(2-methylpropionate)(AIBME) as initiator followed by addition of a certain amounts of iodine in ethanol solution and a gelatin solution. The properties of the film were characterized by infrared(IR), scan electron microscopy(SEM), UV-visible spectroscopy(UV-Vis), differential scanning calorimetry(DSC), etc. The UV-Vis spectrum shows a strong absorption between 200~600 nm for the CTS-PVP film with iodine. The glass transition temperature at 319 ℃ indicates a good thermal stability. The antimicrobial test result shows that the inhibition zone diameters increase along with the increasing amounts of CTS-PVP-I2 complex liquid. The inhibition zone diameters against Staphylococcus aureus and Escherichia coli are in the range of 16~36 mm, when the added volume of CTS-PVP-I2 complex fluid is 10 mL or more, implying its high sensitivity and good antibacterial properties.
Keywords:chitosan  iodine  film  antibacterial properties  functional materials
