Synergistic electro-co-deposition and molecular mixing for reinforcement of multi-walled carbon nanotube in copper

Carbon nanotube-reinforced copper composite powder was prepared by a modified electro-co-deposition method that was carried out on small diameter (3 mm) tip of the cathode. The deposition was done at room temperature and atmospheric pressure. Samples were prepared under constant stirring by a magnetic stirrer. Transmission and scanning electron microscopy confirms the dispersion of multiwalled carbon nanotubes (MWCNT) in the copper matrix. Dispersion of MWCNTs in copper matrix by this method is very easy and the set up can be easily scaled up for the bulk production of MWCNT reinforced copper powder. The method for the fabrication of MWCNT reinforced copper powder; microstructure and morphology of the powder formed are reported.
