What Are Carbon Nanotubes Doped with 12 wt% Copper (Cu) Nanoparticles?

Carbon Nanotubes Doped with 12 wt% Copper (Cu) Nanoparticles are hybrid nanomaterials combining the excellent electrical, thermal, and mechanical properties of multi-walled carbon nanotubes (MWCNTs) with the conductive and catalytic characteristics of copper nanoparticles. The 12% copper loading ensures enhanced functionality without compromising the structural integrity of the CNTs.
