摘要

摘要采用熔融复合和热压法制备了等规聚丙烯-蒙脱土纳米复合薄膜。研究了有机粘土对各向同性复合薄膜力学性能和拉伸性能的影响。含有2.5 wt% MMT的固态拉伸PP带的最终性能优于纯PP带。有趣的是,这些改进被发现并不是纳米粘土薄片的机械强化效应的结果,而仅仅是MMT作为一种更有效的超拉伸机制的结果,这种机制改变了聚合物的初始形态和拉伸行为。因此,MMT的引入提高了取向纳米复合带的极限拉伸比,从而提高了取向纳米复合带的极限力学性能。图形抽象

Nanoclay assisted ultra-drawing of polypropylene tapes
Abstract Isotactic polypropylene (i-PP) – montmorillonite (MMT) nanocomposite films were prepared by melt-compounding and hot-pressing. The influence of organoclays on the mechanical properties and drawability of these isotropic composite films was investigated. Ultimate properties of solid-state drawn PP tapes incorporating 2.5 wt% MMT outperformed those of pure PP tapes. Interestingly, these improvements were found not to be the result of a mechanical reinforcement effect of the nanoclay platelets but merely the result of a more efficient ultra-drawing mechanism with MMT acting as a processing additive that altered initial polymer morphology and drawing behaviour. Hence, the introduction of MMT resulted in higher ultimate draw ratios and subsequently higher ultimate mechanical properties of the oriented nanocomposite tapes. Graphical Abstract
