The conductivity of the single-walled carbon nanotube is influenced by a plurality of factors, and when the diameter of the single-walled carbon nanotube is less than 6nm, the conductivity of the carbon nanotube is increased along with the reduction of the diameter of the carbon nanotube, and the carbon nanotube can be used as a one-dimensional quantum wire; compared with the carbon nano tube with the end cap at the tail end of the carbon tube, the carbon nano tube with the opening at the tail end has stronger electron transmission capability, so that the single-walled carbon nano tube with small tube diameter (less than 6nm) and two openings at two ends is more beneficial to obviously improving the conductivity of the carbon nano tube/aluminum composite material; in addition, the aspect ratio of the carbon tubes also affects the formation of a conductive network in the aluminum matrix, the smaller the aspect ratio of the carbon tubes is, the less the conductive network is formed, and the larger the aspect ratio of the carbon tubes is, the more the carbon tubes are easily intertwined with each other, so that the carbon tubes are difficult to uniformly disperse in the matrix to form a good conductive network.
On the other hand, the wettability between the carbon nano tube and the metal aluminum is poor, so the interface bonding force between the carbon nano tube and the metal aluminum is weak, when the two materials are simply compounded together, phase separation often exists or a large amount of carbon nano tube aggregates exist in an aluminum matrix, the phenomenon is not favorable for improving the mechanical property of the composite material, but also the conductivity of the composite material is reduced due to the enhancement of an electron scattering effect.
The above-mentioned embodiments are only preferred embodiments of the present invention, and are not intended to limit the embodiments of the present invention, and those skilled in the art can easily make various changes and modifications according to the main concept and spirit of the present invention, so the protection scope of the present invention shall be subject to the protection scope of the claims.
