摘要：

In this article, it is demonstrated that simultaneously strengthened and toughened nanocomposites based on polypropylene/EPDM thermoplastic elastomer (TPO) matrix can be achieved through enhanced adhesion between MWNTs and polymer matrix by using PP grafted multiwalled carbon nanotubes (MWNTs). To improve the interface between filler and matrix, MWNTs were treated with acid, or covalently linked to polypropylene. The chemical and morphological transformation of the modified MWNTs, and its effect on the morphology and mechanical properties of the composites are investigated. The strengthening and toughening mechanism is discussed regarding the structural property relationship. (C) 2011 Wiley Periodicals, Inc. J Appl Polym Sci 121: 2104-2112, 2011
