In those previous papers, the contents of filled nanoparticles
were relatively low, the studies on the high nanoparticle
contents were less. So in this paper, the morphology and
mechanical properties of PP nanocomposites filled with low and
high contents of nano-CaCO3 were studied, and three PP
matrices with different intrinsic toughness were used, in order to
find the influence of PP matrix on the mechanical properties of
nanocomposites.
