用AlCl3中心点6H(2)O水溶液溶解壳聚糖(CS)，制备了CS/聚乙烯醇(PVA)共混膜。将AlCl3中心点6H(2)O保留在CS/PVA膜中，并加入甘油，与AlCl3中心点6H(2)O形成复合增塑剂。用原子力显微镜、X射线衍射仪、热重分析和拉伸试验研究了甘油对掺杂AlCl3中心点6H(2)O的CS/PVA膜的吸水率、结晶性能、热性能和力学性能的影响。实验结果表明，甘油对AlCl3中心点6H(2)O掺杂的CS/PVA薄膜的性能有显著的促进作用。在AlCl3中心点6H(2)O和甘油的协同作用下，制备的CS/PVA薄膜具有优异的力学性能。当添加30wt%的甘油时，AlCl3中心点6H2O掺杂的CS/PVA薄膜的拉伸强度和断裂伸长率分别达到39 Mpa和120%。(C)2015爱思唯尔有限公司。保留所有权利。
The AlCl3 center dot 6H(2)O aqueous solution was used to dissolve chitosan (CS) and the CS/poly(vinyl alcohol) (PVA) blend films were prepared at the absence of acetic acid. AlCl3 center dot 6H(2)O was retained in CS/PVA film and glycerol was added to form the complex plasticizer with AlCl3 center dot 6H(2)O. The effect of glycerol on the water sorption, crystalline, thermal and mechanical properties of AlCl3 center dot 6H(2)O doped CS/PVA film was studied by atomic force microscopy, X-ray diffraction, thermal gravity analysis and tensile testing, respectively. The experimental results showed that glycerol had a significant positive effect on the properties of AlCl3 center dot 6H(2)O doped CS/PVA films. With the synergism effect of AlCl3 center dot 6H(2)O and glycerol, the prepared CS/PVA films showed excellent mechanical properties. With the addition of 30 wt% glycerol, the AlCl3 center dot 6H(2)O doped CS/PVA films behave the tensile strength of 39 MPa and elongation at break of 120%, respectively. (C) 2015 Elsevier Ltd.
