摘要：采用流延法制备了高含量玉米醇溶蛋白（Zein）的 Zein/壳聚糖（CS）复合膜，考察了复合添加剂〔m（甘
油）∶m（聚乙二醇 400）=1∶1〕添加量（以总溶液质量计，下同）对 Zein/CS 复合膜力学、光学和热学性能
的影响。通过 SEM、FTIR、DSC 对 Zein/CS 复合膜进行了表征。结果表明，复合添加剂通过削弱 Zein 和 CS 之
间的分子间作用力，达到增塑效果，Zein/CS 复合膜综合机械性能有所改善，随着复合添加剂添加量的升高，
Zein/CS 复合膜断裂伸长率逐渐增强，拉伸强度呈先降后升的趋势；水蒸气透过率（WVP）逐渐增加，水接触
角逐渐减小，Zein/CS 复合膜的亲水性随之增强。与不含复合添加剂的薄膜（ZC-0）相比，当复合添加剂添加量
为 1.5%时，Zein/CS 复合膜（ZC-1.5）的拉伸强度降低了 27.47%，断裂伸长率增长了 24.61%，WVP 上升了 29.18%。
制备的 Zein/CS 复合膜表面更加平整光滑。在 ZC-1.5 复合膜中添加了一定量的姜黄素，能够有效提高 Zein/CS
复合膜的抗氧化活性至 55.18%±0.16%。

Abstract: Zein/chitosan (CS) composite film with high content of zein was prepared via casting
method, and characterized by SEM, FTIR and DSC. The effects of composite additive [m(glycerol)∶
m(PEG 400)=1∶1] additive amount (based on the mass of total solution, the same below) on the
mechanical, optical and thermal properties of Zein/CS composite film were then investigated. The results
showed that the composite additives achieved the plasticizing effect by weakening the intermolecular force
between zein and CS, and improved the comprehensive mechanical properties of Zein/CS composite film.
Moreover, with additive amount of composite additive increased, Zein/CS composite film exhibited a trend
of gradual increase in the elongation at break, first decrease then increase in tensile strength, gradual
increase in the water vapor permeability (WVP), gradual decrease in water contact angle, and enhancement
in hydrophilicity. Compared with the film without composite additives (ZC-0), the tensile strength of
Zein/CS composite film (ZC-1.5) with 1.5% composite additives decreased by 27.47%, the elongation at
break increased by 24.61%, and the WVP increased by 29.18%. Meanwhile, the prepared Zein/CS
composite film displayed much smoother surface. In addition, a certain amount of curcumin added to
