Curcumin incorporated poly(butylene adipate-co-terephthalate) (PBAT) based film was fabricated. Curcumin has uniformly distributed in the PBAT matrix to form a bright yellow PBAT/curcumin film. The PBAT/curcumin film has slightly reduced tensile strength and flexibility than the neat PBAT film, while the thermal stability of the film has not changed significantly. The blending of curcumin significantly decreased the water vapor permeability of the PBAT film. Additionally, the PBAT/curcumin film showed potent antioxidant activity with some antimicrobial activity. The PBAT/curcumin films with improved water vapor barrier and additional functions can be used for active packaging applications.
制备了含姜黄素的聚(己二酸丁二醇酯-对苯二甲酸丁二醇酯)(PBAT)基薄膜。姜黄素均匀分布在PBAT基体中,形成亮黄色的PBAT/姜黄素薄膜。PBAT/姜黄素薄膜的拉伸强度和柔韧性比纯PBAT薄膜略有降低,而薄膜的热稳定性没有显著变化。姜黄素的掺入显著降低了PBAT薄膜的水蒸气透过率。此外,PBAT/姜黄素薄膜表现出较强的抗氧化活性和一定的抗菌活性。具有改进的水蒸气阻隔性能和附加功能的PBAT/姜黄素薄膜可用于活性包装应用。
