Abstract

Introduction of nanocarbon into metal matrices has shown promising improvement over the base metals. In this study, we examine the effect of a new nanocarbon phase – carbonized polydopamine (cPDA) – on the electrical, thermal, and mechanical properties of sintered copper. The composite samples exhibited better electrical conductivity, thermal diffusivity, hardness and wear resistance. Composites with a low cPDA concentration (0.4 vol%) possessed the best electrical conductivity and mechanical properties, while composite samples with higher cPDA concentrations (3.5 vol %) showed significantly enhanced thermal diffusivity as high as 104.5 mm²/s that is 63.5% higher than the sintered Cu sample.
