| Abstract Scope |
Carbon nanotube (CNT) possesses remarkably high thermal and electrical conductivities which makes it an excellent material for light-weight electrically and thermally conductive components. However, translating these nanoscale properties into balk samples has been challenging. One promising solution is fabrication of CNT-Cu composites with high CNT loading. Inherently, these two materials have weak interactions and hence poor bonding. In this work, the effect of CNT surface modification on the morphology, composition, and electrical and thermal properties Cu/CNT composites was studied. For this purpose, the surface of CNTs was functionalized with different surface treatments. These CNTs were used as substrate for growth of copper via a facile electrochemical process. It is observed that by changing the surface functional group on CNT, the morphology and chemical state of the Cu deposits can be controlled. Moreover, thermal and electrical conductivity of CNT-Cu thin films as a function of CNT surface treatment were evaluated. |
