摘要: 优选一种有机蒙脱土(OMMT),在不加任何相容剂的情况下,利用熔融挤出法直接复合制备出了高密度聚乙烯惰‘机蒙脱土(PE-HD/OMMT)纳米复合材料。利用透射电子显微镜观察发现制备出了剥离型的纳米复合材料,分析了蒙脱土片层的气体阻透性机理;对复合材料制备的复合薄膜透气性测试结果表明,氧气渗透率降低了37%。通过真空测试发现由纳米复合材料制备的保鲜袋的真空保留期由纯聚乙烯的1d延长到18 d,显示了纳米蒙脱土片层的超强阻透效果。

Abstract: PoyethylencPE)/OMMT nanocomposites were prepared via melt extrusion without using a compatibilizer.Transmission electron microscopy(TEM) confirmed that an exfoliated structure of OMMT wasobtained.Thegas permeationtests showed that the oxygen penetration in the nanocompos-ite film decreased by 37%. The vacuum degree holding times of nanocomposits bags increased from one to eighteendays.The crystallization behavior andthermostability of the nanocomposites were also stud ied using DSC and TGA.

Key words: high density polyethylene, organic montmorillonite, nanomposite, barrier property;themzostabifity
