Nanocarbon fiber has good conductivity, mainly for the following reasons:

Unique structure: carbon nanofibers have a graphitic microstructure, and the internal carbon atoms form covalent bonds in a sp-2 hybrid way, forming a hexagonal planar network structure. This structure provides a good channel for electron delocalization and conduction, making electrons move relatively freely inside the carbon fiber, thus showing good conductivity properties.

High specific surface area: Nanocarbon fiber has a large specific surface area, which means that there are a large number of unsaturated bonds and suspended bonds on its surface, which can interact with other substances, thereby increasing the transmission path and opportunity of electrons, which is conducive to improving conductivity.

Quantum size effect: The quantum size effect occurs when the size of a material is reduced to the nanometer scale. For carbon nanofibers, this effect will lead to changes in their electronic structure, increase the energy level spacing of electrons, increase the mobility of electrons, a
