CEOs/HNTs/PBAT复合薄膜的制备及其性能研究
Preparation and properties of CEOs/HNTs/PBAT composite films
摘要
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.关键词
