Abstract
The present invention provides a process for manufacturing a carbon nanofiber comprising: (a) mixing a carbon nanofiber precursor and camphor in a solvent to prepare a solution; (b) electric spinning the solution to obtain a nanofiber; (c) oxidative stabilizing the nanofiber; and (d) carbonizing the oxidative stabilized nanofiber, wherein camphor is volatilized to form micropores in the oxidative stabilization and carbonization. The present invention also provides a carbon nanofiber manufactured by the same.
Claims6
A process for manufacturing a carbon nanofiber comprising:
- mixing a carbon nanofiber precursor and camphor in a solvent to prepare a solution;
- electric spinning the solution to obtain a nanofiber;
- oxidative stabilizing the nanofiber to release the camphor from the nanofiber, thereby forming micropores at the surface of the nanofiber;
- and
- carbonizing the oxidative stabilized nanofiber to release any camphor that has not been released by the oxidative stabilization process, thereby forming further micropores at the surface of the nanofiber.
