The influence of incorporating organic modified nanoclay (Cloisite 10A) (C 10A) on the morphology, interfacial characteristics, and physico-mechanical properties of polypropylene (PP) melt blended with natural rubber (NR) is investigated here. Melt-mixing technique was employed to prepare nanocomposites with varying amounts of C 10A (1, 3, 5, 7 phr). Nanoclay, depending on its concentration, ‘instigated dramatic transformation of phase morphology from a co-continuous type to a non-uniform sea-island type leading to well-defined matrix-droplet morphology. Besides, addition of nanoclay refined the phase morphology and effectuated synergistic improvement in physico-mechanical properties, where 3 wt% nanoclay modified system exhibited optimal properties for end use application in automotive industry thereby establishing the morphology-property correlation.

本文研究了掺入有机改性纳米粘土（Cloisite 10A）（C 10A）对与天然橡胶（NR）熔融共混的聚丙烯（PP）的形态，界面特性和物理力学性能的影响。采用熔体混合技术制备了具有变化量的C 10A（1、3、5、7 phr）的纳米复合材料。纳米粘土，取决于其浓度，“促使相形态从共连续型向非均匀海岛型急剧转变，从而导致基质-液滴的形态清晰。此外，纳米粘土的加入改善了相形貌并实现了物理机械性能的协同改善，
