Abstract

The highest amount of the world's polyethylene terephthalate (PET) is designated for fiber production (more than 60%) and food packaging (30%) and it is one of the major polluting polymers. Although there is a great interest in recycling PET-based materials, a large amount of unrecycled material is derived mostly from the food and textile industries. The aim of this study was to obtain and characterize nanostructured membranes with fibrillar consistency based on recycled PET and nanoparticles (FeO@UA) using the electrospinning technique. The obtained fibers limit microbial colonization and the development of biofilms. Such fibers could significantly impact modern food packaging and the design of improved textile fibers with antimicrobial effects and good biocompatibility. In conclusion, this study suggests an alternative for PET recycling and further applies it in the development of antimicrobial biomaterials.

摘要

世界上聚对苯二甲酸乙二酯（PET）产量最高的用途是纤维生产（超过60%）和食品包装（30%），它是主要的污染性聚合物之一。尽管人们对回收PET基材料很感兴趣，但大量未回收材料主要来自食品和纺织行业。本研究的目的是使用静电纺丝技术，制备并表征基于回收PET和纳米颗粒（FeO@UA）的具有纤维状结构的纳米结构膜。所获得的纤维可限制微生物定殖和生物膜的形成。这类纤维可能会对现代食品包装以及具有抗菌效果和良好生物相容性的改良纺织纤维的设计产生重大影响。总之，本研究提出了一种PET回收利用的替代方案，并将其进一步应用于抗菌生物材料的开发。
