摘　　要：用乙烯-乙烯醇共聚物(EVOH)、聚酰胺6(PA6)及聚乙烯(PE)制备了多层复合膜,并研究其力学性能、热学性能以及阻隔性能。结果表明:复合后其弹性模量和屈服强度降低,而延展性得到了大幅提高。在高湿度下复合膜仍保持较高的氧气阻隔性和水蒸气阻隔性。The composite films were prepared by using ethylene-vinyl alcohol copolymers （EVOH）, polyamide 6（PA6） and polyethylene（PE） multilayer, and the mechanical, thermal and barrier properties of films were characterized. The results show that： the modulus of elasticity and yield strength decrease, but the ductility of composite film improves greatly. In addition, the composite films remain high oxygen and water vapor barrier properties under high humidity.
