INFLUENCE OF MELT VISCOSITY ON THE PROPERTIES OF POLYPROPYLENE/CARBON NANOTUBE NANOCOMPOSITES OBTAINED BY MELT MIXING PROCESS

摘要

Multiwall carbon nanotubes (MWCNTs) are widely studied and applied as a nanometric, high aspect ratio conductive filler for polymers. In this study, the formulation of a concentrate polypropylene (PP) based masterbatch and the influence of the melt viscosity of different PP matrices during dilution step on the dispersion and properties of PP/MWCNTs composites have been investigated, both analyzing materials nanostructure and macroscale physical properties.
