Abstract

In this study, the electrical and thermal performance of composite wires made of copper coated with single-walled carbon nanotubes and a thermally conductive resin was investigated. Raman spectroscopy confirmed the successful synthesis of single-walled carbon nanotubes with an ordered crystalline structure, and scanning electron microscopy revealed a uniform distribution of the nanotubes and resin layer on the copper wire surface. The results from the resistivity and temperature versus current density and current intensity plots demonstrated that the composite wire outperformed the reference copper wire. Specifically, it exhibited lower resistivity at high current levels and maintained structural stability at higher temperatures. This enhanced performance can be attributed to the high electrical and thermal conductivity of the nanotubes, as well as the resin's stabilizing and heat-dissipating properties. Overall, the integration of carbon nanotubes and conductive resin into copper wire structures significantly improves thermal stability and current-carrying capacity, making this composite highly suitable for high-power applications, transmission lines, and sensitive electronic systems.
