Abstract

A continuous, industrially scalable process method called solid-state shear pulverization is shown to be effective in producing well-dispersed polypropylene/ carbon nanotube and polypropylene/ as-received graphite nanocomposites that cannot be obtained by conventional melt processing alone. Major improvements in Young's modulus (> 100% increase) and yield strength (65% increase) are obtained in the nanocomposites made by SSSP, with the maximum increases being observed in samples containing the highest concentrations of nanofiller that are well-dispersed. In contrast, electrical conductivity is correlated to dispersion of carbon-based nanofiller in a different manner, with conductivity increasing with increasing nanofiller content even when an increase in nanofiller content results in less effective dispersion or exfoliation.
