摘要：
Chitosan films plasticized with the complex of AlCl(3)6H(2)O and glycerol were prepared by using AlCl(3)6H(2)O as the solvent. The effect of AlCl(3)6H(2)O and glycerol complex with Chitosan was studied by SEM, XRD, TGA, and tensile testing. The complex would increase the water resistance and destroy the crystals of chitosan film. The TGA results proved that the chitosan film plasticized with the complex showed higher thermal stability at the temperature below 200 degrees C than pure chitosan film. With the addition of the complex of AlCl(3)6H(2)O and glycerol, the tensile strength of chitosan film decreased and the elongation at break increased.
