Abstract:
The Al(NO3)3·9H2O aqueous solution was used to dissolve chitosan and the chitosan films were prepared by solution casting. Glycerol was added to plasticize chitosan film. The optical, crystalline and mechanical properties of chitosan films were tested by X-ray diffraction, UV-Vis spectrum and tensile testing respectively. The results show that chitosan could be dissolved in the Al(NO3)3·9H2O aqueous solution, but the higher amount of Al(NO3)3·9H2O would lead to loss of film forming ability of chitosan. The appropriate amount of Al(NO3)3·9H2O for chitosan is 75% (mass fraction). The addition of glycerol could increase the transmittance of Al(NO3)3·9H2O doped chitosan film. However, the transmittance of Al(NO3)3·9H2O doped chitosan film would decrease with the increasing amount of glycerol. The XRD results show that the addition of glycerol would increase the crystallinity of Al(NO3)3·9H2O doped chitosan film. The tensile testing results show that the glycerol would increase the elongation at break of chitosan film and decrease the tensile strength. ©, 2015, Chengdu University of Science and Technology.
