Multi-wall carbon nanotubes (MWNTs) were modified by laser ablation of Cu, Ti and TiN in the presence of He, O-2 and N-2 buffer gases. The sizes of Cu, TiO2 and TiN particles and their agglomerated structures were varied dependent on types of the particles and surface proper-ties of MWNTs. An ultrasonication treatment of as-grown MWNTs was very effective to attach the agglomerated nanoparticles to MWNTs. We discuss the distribution and morphology of the particles from the arrival of clusters and nanoparticles formed in gas-phase and the surface properties of MWNTs.
