Changes in The Mechanical Properties of Polypropylene by Addition two Types of Nanofillers: Carbon Nanotubes and Organoclay

The present work is focused on the mechanical characterization of the prepared via extrusion mixing hybrid nanocomposites composed from two different nanofillers in polymer matrix. These nanocomposites include organoclay (OC) and multiwall carbon nanotubes (MWCNTs) in various combinations as fillers in an isotactic polypropylene (iPP) matrix. Three-phase polypropylene nanocomposites give comprehensive information about the macro-, micro- and nano-mechanical properties and provide information for better understanding the extent of reinforcement via nanoparticles. The carried out experiments give good overview of the changes in modulus of elasticity and elongation at maximum strength as well as scratch coefficient of friction, nano hardness and Young’s modulus with variation of the fillers concentrations. Keywords: polypropylene, nanofillers, mechanical properties, three-phase nanocomposites
