Dependence of secondary operations in powder metallurgy and their impact on the electrical conductivity of MWCNTs/Cu nanocomposites

This study reports the electrical conductivity of multi-wall carbon nanotubes (MWCNTs) embedded copper nanocomposites. Copper-based nanocomposites are prepared by the powder metallurgy route method with two different secondary operations, (i) hot pressing and (ii) rolling. The MWCNTs doping weight percentage used are 0, 0.25, 0.5, 0.75 and 1 wt% of copper (or base material). The four-point probe technique is used to measure the electrical...
