Abstract:

Carbon nanotubes (CNTs) reinforced copper powder was synthesized by a chemical based route named as molecular level mixing. Starting from copper acetate monohydrate mixed with carbon nanotubes in ethanol followed by drying, calcination, and reduction steps resulted in copper nanoparticles with uniform distribution of reinforcing carbon nanotubes. The process is characterized at each step by Fourier transform infrared spectroscopy (FTIR), X-ray diffraction, and scanning electron microscopy (SEM). Emphasis is placed on the functionalization of carbon nanotubes and its role in deagglomeration and uniform mixing with metal matrix. Sintering of the powder was done at 900°C for 2 hours and SEM studies revealed good retention and uniform distribution of carbon nanotubes in copper matrix of the nanocomposite materials.
