Halloysite nanotubes (HNTs) were loaded with lsozyme, as antimicrobial molecule, at a HNTs/lysozyme ratio of 1:1. Such a nano-hybrid was incorporated into a poly (-caprolactone) (PCL) matrix at 10 wt % and films were obtained. The nano-composites were submitted to a cold drawn process at three different draw ratios, = 3, 4, and 5, where is /. Morphology, physical, and barrier properties of the starting nanocomposite and drawn samples were studied, and correlated to the release of the lysozyme molecule. It was demonstrated that with a simple mechanical treatment it is possible to obtain controlled release systems for specific active packaging requirements.
将埃洛石纳米管（HNTs）与作为抗菌分子的溶菌酶以1:1的HNTs/溶菌酶比例进行负载。将这种纳米杂化物以10重量%的比例掺入聚（ε-己内酯）（PCL）基质中，从而获得薄膜。对纳米复合材料在三种不同拉伸比（λ = 3、4和5，其中λ为l / l₀）下进行冷拉伸处理。研究了初始纳米复合材料和拉伸样品的形态、物理及阻隔性能，并将其与溶菌酶分子的释放相关联。结果表明，通过简单的机械处理就有可能获得满足特定活性包装要求的控释系统。
