Abstract Carbon nanotubes (CNTs) reinforced copper (CNTs/Cu) is one of the most promising and extensively researched materials for replacing traditional Cu-based materials in high-load and high-current applications, particularly within the aerospace industry. Amorphous carbon nanotubes (aCNTs) are a type of carbon nanotubes characterized by the presence of mesopores distributed across their amorphous sidewalls, facilitating connectivity between the hollow core and the external environment. Therefore, we propose utilizing aCNTs as a reinforcing agent for Cu. The mesoporous structure of aCNTs facilitates the interpenetration of Cu into the aCNTs, thereby maintaining the continuity of the matrix properties. Experimental results demonstrate that Cu effectively penetrates the mesoporous sidewalls of aCNTs. Both pure Cu and aCNTs-reinforced Cu exhibit comparable electrical conductivity, while the hardness of the aCNTs/Cu composite is significantly enhanced. Additionally, both the density and porosity of aCNTs/Cu are lower than those of pure Cu, and the introduction of aCNTs helps to reduce the sintering temperature.

Altmetric calculates a score based on the online attention an article receives. Each coloured thread in the circle represents a different type of online attention. The number in the centre is the Altmetric score. Social media and mainstream news media are the main sources that calculate the score. Reference managers such as Mendeley are also tracked but do not contribute to the score. Older articles often score higher because they have had more time to get noticed. To account for this, Altmetric has included the context data for other articles of a similar age.
