摘　　要：为探究丁香精油和酸刻蚀埃洛石纳米管(halloysite nanotubes,HNTs)/丁香精油混合负载物(HNTs-4Mclove)对PBAT/PPC复合薄膜性能的影响,首先对HNTs进行酸刻蚀处理,然后将丁香精油与酸刻蚀HNTs负载混合,得到HNTs-4M-clove。丁香精油和HNTs/丁香精油混合负载物的加入使薄膜呈现黄绿色,薄膜的透明性和气体阻隔性略有下降,但对大肠杆菌、金黄色葡萄球菌和腐败希瓦氏菌展现出良好的抗菌性。相较于仅添加丁香精油的薄膜,含HNTs/丁香精油的薄膜在抗拉强度和气体阻隔性方面有所提升。同时,HNTs有助于丁香精油在薄膜中的分散,在一定程度上减缓了丁香精油的释放。因此,酸刻蚀HNTs/丁香精油混合负载物不仅赋予PBAT/PPC薄膜良好的抗菌性,还可减缓薄膜中丁香精油的释放,为可降解缓释型活性包装薄膜的开发提供了参考。To elucidate the effects of clove essential oil or acid-etch halloysite nanotubes/clove oil(HNTs-4Mclove)on the properties of poly-butylene adipate-co-terephthalate/poly-propylene carbonate(PBAT/PPC)composite films,HNTs-4M-clove was obtained by mixing the acid-etched HNTs with clove essential oil.With the addition of clove essential oil or HNTs-4M-clove,the color of the films became yellow-green,and their transparency and gas barrier properties decreased,while the films exhibited good antibacterial activity against Escherichia coli,Staphylococcus aureus and Sivarella putrefaciens.The film containing HNTs-4M-clove demonstrated higher tensile strength and gas barrier properties compared to the film with clove essential oil.Additionally,HNTs promoted the dispersion of clove essential oil in the film and slowed down its release rate.Therefore,HNTs-4M-clove gave the PBAT/PPC film a good antibacterial activity with a retarded release rate of clove essential oil,which provided a reference for the development of biodegradable slowed-release active packaging film.
