Abstract

The CNTs are of great interest because of their unique complete properties of matter, especially, the large thermal conductivity (Thermal conductivity of CNTs ~ >2000W /mK vs. Thermal conductivity of Aluminum ~ >204W/mK). However, owing to the strong agglomeration cause by the vander wall's force, the CNTs are limited to applicate. In this study. we suggest a new method for CNTs dispersion. which are developed by the mechanical and chemical method. and then Cu was coated. This new process produces CNTs/Cu nanocomposite powders. The CNTs are homogeneously located within the Cu powders by chemical reaction. And the thermal properties of the CNTs/Cu nanocomposite were investigated.
