摘要
通过溶液法制备了不同比例的聚己内酯/α-环糊精(PCL/α-CD)络合物,并通过热压法制备了PCL/α-CD络合物薄膜。分别使用傅里叶变换红外光谱仪(ATR-FTIR)、差示扫描量热分析仪(DSC)、透湿仪和透氧仪对不同比例的PCL/α-CD络合物薄膜的热性能、力学性能及阻隔性能进行研究。红外数据表明PCL和α-CD同时存在于络合物中。随着α-CD含量的增加,PCL/α-CD络合物的结晶度逐渐降低,薄膜的氧气阻隔性和水蒸气阻隔性逐渐增加,并且薄膜的氧气阻隔性增加的效果大于水蒸气阻隔性增加的效果。
PCL with α-CD inclusion complex (PCLIC) film was prepared by solution method with different ratios, and PCLIC film was prepared through hot-pressing method. The thermal, mechanical and barrier properties of PCLIC films were characterized by attenuated total reflectance fourier transformed infrared (ATR-FTIR), differential scanning calorimetry(DSC), oxygen and moisture permeation analyzer. The ATR-FTIR reveals that PCL and α-CD coexist in complexes. With increasing the content of α-CD, the crystallinity of PCL decreases. The oxygen and water vapor barrier properties of PCLIC film gradually increase with the increasing of α-CD content, and then the effect of oxygen barrier increases larger than that of water vapor barrier.
