Composite carbon fibers |
摘要 |
Provided is composite carbon fibers comprising multi-walled carbon nanotubes wherein 99% by number or more of the multi-walled carbon nanotubes have a fiber diameter of not less than 5 nm and not more than 40 nm, carbon particles having a primary particle diameter of not less than 20 nm and not more than 100 nm and graphitized carbon nanofibers wherein 99% by number or more of the graphitized carbon nanofibers have a fiber diameter of not less than 50 nm and not more than 300 nm, wherein the multi-walled carbon nanotubes are homogeneously dispersed between the graphitized carbon nanofibers and the carbon particles. |

1. Composite carbon fibers, comprising:
multi-walled carbon nanotubes in which 99% by number or more of the multi-walled carbon nanotubes have a fiber diameter of not less than 5 nm and not more than 40 nm, carbon particles having a primary particle diameter of not less than 20 nm and not more than 100 nm, and graphitized carbon nanofibers in which 99% by number or more of the graphitized carbon nanofibers have a fiber diameter of not less than 50 nm and not more than 300 nm, wherein the graphitized carbon nanofibers and the carbon particles are present in a space between the multi-walled carbon nanotubes untangled into a loosened state, and the multi-walled carbon nanotubes in the untangled state are entangled on the surfaces of the graphitized carbon nanofibers and the carbon particles. |
