| 摘 要： | 本文通过熔融共混和模压技术制备得到纳米氧化锌／高密度聚乙烯（纳米-ZnO／HDPE）复合膜，并考察了该膜的微观形态、机械性能、结晶性能以及阻隔性。结果发现，复合膜中改性纳米ZnO的含量较低（0．5wt％）时，纳米ZnO在HDPE中具有较好的分散性。随着改性纳米ZnO含量的增加，复合膜的拉伸强度和撕裂强度先增大后减小，ZnO含量为0．5wt％时，综合力学性能最佳。此外，改性纳米ZnO的添加能提高HDPE的结晶度，并能增强复合膜的阻隔性能。

| Abstract: | In this paper, nanocomposite film of ZnO/HDPE was prepared via melt blending and hot compression molding process. The morphology, DSC, mechanical and barrier properties of the film were also investigated. The results showed that a better dispersion of modified nanoparticles occurred at content of 0. 5wt% in HDPE matrix, and as modified-ZnO nanoparticles increase, tensile strength and tear strength of composite films would first increase then decrease. When modified - ZnO nanoparticles was up to 0. 5wt%, composite film has optimized comprehensive mechanical properties. It was also found that the addition of modified nano-ZnO would increase HDPE crystallinity and enhance the barrier property of nano-ZnO/ HDPE composite films. |
