摘要:
为了延长食品的货架期和减少白色污染，利用埃洛石纳米管（HNTs）负载肉桂精油（CEOs）得到CEOs/HNTs纳米粒子。将其添加到聚己二酸/对苯二甲酸丁二醇酯（PBAT）树脂中，进行熔融共混挤出，制备出具有抗菌效果的复合薄膜。热重分析表明HNTs对CEOs的初始负载率约为10%；场发射扫描电子显微镜显示HNTs长度为500~1 500 nm，直径为50~100 nm，CEOs/HNTs纳米粒子均匀地分散在PBAT薄膜中。与PBAT薄膜相比，CEOs/HNTs/PBAT复合薄膜的力学性能得到提高，透光和透水等物理性能在一定程度上得到改善。对金黄色葡萄球菌和大肠杆菌的抗菌效果可以达到93%和97%。同时在对草莓的保鲜试验中，取得了很好的保鲜效果。
Abstract:
To prolong the shelf life of food and reduce plastic pollution，halloysite nanotubes were loaded with cinnamon essential oils（CEOs/HNTs）. Then，the CEOs/HNTs were added to poly(butyleneadipate-co-terephthalate) （PBAT） resin and melted，blended and extruded to prepare composite films with antibacterial effects. Thermogravimetric analysis shows that the loading rate of the halloysite nanotubes is about 10%. The results of field emission scanning electron microscope indicate the length of the HNTs is 500-1 500 nm and the diameter is 50-100 nm. Also，CEOs/HNTs nanoparticles are evenly distributed in the PBAT resin. Compared with PBAT films，the mechanical properties of CEOs/HNTs/PBAT composite films are improved，and the physical properties such as light and water transmission are improved to a certain extent. The antibacterial activity against Staphylococcus aureus and Escherichia coli reached 93% and 97%，respectively. At the same time，a good freshness-keeping effect was obtained in the freshness-keeping experiment of strawberry.
