Abstract

There have been extensive efforts to improve the properties of conventional metals such as electrical conductivity and rigidity. Here, we report a massive fabrication strategy for metal-carbon nanotube (CNT) laminate-based electrodes. In this method, CNTs were assembled by directed assembly strategy and a thin metal layer was formed by electrodeposition process, and those processes were repeated several times to fabricate multilayered structures. We demonstrated that metal-CNT laminates showed 42% enhancement in the conductivity compared to electrodeposited metals. Furthermore, its Young's modulus was found to be 88% higher than pure bulk metals. Interestingly, the fabricated structures show I-V characteristics of metal wires while exhibiting typical noise characteristics of CNTs. Since our method uses only conventional microfabrication facilities, it can be readily used by the present microfabrication industry.
