Abstract Various combinations of matrix, filler and classical additives lead to wide possibilities of improving material specifications for mechanical, thermal and structural properties. The studied samples were prepared from a primary polyethylene (PE) layer coated with a thin film of polycaprolactone (PCL) and modified with magnetite, casein/magnetite and zeolite/magnetite compounds. Enhancements to mechanical properties were observed, especially tensile strength and thermal properties for bilayer PE/PCL films prepared using casein and magnetite (Fe3O4) compounds. Adding various modifiers increased the melting and crystallization enthalpy, indicating an increase in PE crystallinity and changes to thermal transitions of bilayer PE/PCL modified films.

修饰符的效果；酪蛋白、沸石和磁铁矿对双层聚乙烯/聚己内酯薄膜性能的影响

摘要 基体、填料和经典添加剂的各种组合为改善材料的机械、热和结构性能规格提供了广泛的可能性。所研究的样品由涂覆有聚己内酯 (PCL) 薄膜并用磁铁矿、酪蛋白/磁铁矿和沸石/磁铁矿化合物改性的初级聚乙烯 (PE) 层制备。观察到机械性能的增强，特别是使用酪蛋白和磁铁矿 (Fe3O4) 化合物制备的双层 PE/PCL 薄膜的拉伸强度和热性能。添加各种改性剂增加了熔化和结晶焓，表明 PE 结晶度增加和双层 PE/PCL 改性薄膜的热转变发生变化。
