本研究基于层层组装流延法制备了载有氧化锌纳米颗粒的海藻酸钠/壳聚糖双层复合膜。通过评价机械、阻水及光学性质研究了氧化锌纳米颗粒对双层复合膜特性的影响,进而借助原子力显微镜、扫描电子显微镜、傅里叶变换红外光谱和热重分析对双层复合膜结构进行表征。结果表明,海藻酸钠/壳聚糖双层膜在添加氧化锌纳米颗粒后,抗拉强度提高,断裂伸长率、水溶性、水蒸气透过性和透光性降低,而外观色泽没有明显变化。从双层膜的微观结构看,随着氧化锌纳米颗粒添加浓度由0.25%(w/w)增加至1.00%(w/w),海藻酸钠/壳聚糖双层复合膜表面出现颗粒团聚,粗糙度Ra从3.12 nm增加至3.53 nm。红外和热重分析表明,氧化锌纳米颗粒与海藻酸钠和壳聚糖之间存在较强的氢键相互作用,使得双层复合膜的热稳定性增强。综上,氧化锌纳米颗粒-海藻酸钠/壳聚糖双层复合膜具有优良的包装特性和适用性。
