Abstract:

In this study, metallic constantan Cu55-Ni44-Mn1 wt alloy substrates were investigated as an alternate choice of substrates to grow carbon nanotubes CNTs. No additional catalysts were used other than the as-rolled and annealed substrates to process CNTs on them. High density CNT growth was observed to take place on these substrates when suitable conditions were used in a thermal chemical vapor deposition CVD furnace with C2H2 as the carbon precursor. Scanning electron microscopy and transmission electron microscopy on these samples indicated the presence of several micron long CNTs ranging in 20 to 100 nanometers in diameter. Raman spectra taken from the samples confirmed the presence of G band peaks peak at approx. 1580 cmexp -1 and D band peaks peak at approx. 1320 cmexp -1 commonly observed in CVD grown multiwall CNT samples varying intensity.
