Influence of exfoliated carbon nanotubes on crystal structure and tensile properties of polypropylene Conference Paper uri icon

abstract

  • The objective of this work is to investigate the microstructural mechanisms responsible for the observed remarkable increase in modulus and strength of polypropylene (PP) containing only trace amounts of multi-walled carbon nanotubes (MWCNTs). The functionalized MWCNTs were individually dispersed in commercial polypropylene matrix by using our novel nanoplatelet-assistcd dispersion approach, followed by compatibilization of MWCNT in a small amount of stabilizing surfactant. We also report on the morphology and dynamic mechanical properties, and propose a novel mechanism for reinforcement of thermoplastic materials with individual MWCNTs.
