增塑剂对壳聚糖/纳米蒙脱土复合膜物理性能的影响

摘要

The objective of this paper was to investigate the effect of plasticizer on properties of chitosan/nano-montmorillonite film. The results showed that plasticizer had significant effect on the properties of the film. It reduced the tensile strength and light transmittance, significantly increased the elongation at the break, and increased the water vapor permeability and water absorption.%研究了增塑剂(甘油、聚乙二醇400、山梨醇)对壳聚糖/纳米蒙脱土复合膜物理性能的影响.结果表明:加入增塑剂对复合膜的性能有显著的影响,可降低膜的拉伸强度和透光率,显著提高膜的断裂伸长率,并增大了膜的水蒸气透过率和吸水率.
