Abstract

The interfacial bonding strength between carbon nanotubes (CNTs) and the metal matrix in CNT/metal composites can be increased by depositing metal or metal oxide particles onto the CNT surface. In this study, the effect of the supported amorphous Al₂O₃ nanoparticles on the tensile strength of individual multi-walled CNTs (MWCNTs) synthesized by chemical vapor deposition has been investigated in situ by scanning electron microscopy. The average tensile strength of MWCNTs with supported amorphous Al₂O₃ nanoparticles was slightly higher than that of the as-grown MWCNTs, which could be attributed to the interactions between the supported materials and the CNT defect sites.
