An Investigation on the Microstructure of CNT-Reinforced PP/PC Nanocomposites

Polypropylene(PP)/Polycarbonate(PC) nanocomposites reinforced with carbon nanotubes (CNTs) were prepared using laboratory internal mixer at 255°C in order to investigate CNT dispersion, mechanical and structural properties of the prepared nanocomposites at different blend composition ratios. Results showed that upon the addition of CNT to PP/PC blend samples the failure mechanism changes from ductile to brittle behavior. Studying the fracture surface of nanocomposite samples through scanning electron microscope revealed some layers developed on the surface indicating heterogeneity in the nanoclay dispersion
