A composite material composed of copper network embedded in a carbon nanotube (CNT) tissue is proposed as an alternative material for electrical conductors. Copper electrodeposition is employed as a simple, cost-efficient preparation method, providing high-purity deposits. Electrodeposition has the potential ability to introduce copper inside the 3D CNT tissue; yet, most of the up-to-date deposition methods are restricted to the external surface of the tissue. This research focuses, among other objectives, on understanding the mechanism of deposition in the system and its tendency to occur inside the tissue rather than outside it.

Copper was successfully electrodeposited inside CNT tissue from multiple aqueous electrolytes. The crucial role and composition of the electrolyte have been studied, and various electrolytes were characterized and categorized according to their ability to facilitate deposition inside the CNT tissue. Other key parameters for a successful process were identified and have provided new insights and a deeper understanding of the governing mechanisms and limiting factors in the system. These principles can now be further adapted to other systems, enabling the synthesis of distinct metal-CNT composite materials.
