Abstract
The present invention discloses an ultrafine graphitic carbon fiber and a preparation method thereof. An ultrafine fiber having a diameter of 1 to 3000 nm is prepared by electrospinning a halogenated polymer solution containing a metal compound inducing graphitization. In carbonization, an ultrafine porous graphitic carbon fiber having a large specific surface area, micropores and macropores is prepared by the graphitization by a metal catalyst generated from the metal compound. The ultrafine carbon fiber can be used as a carbon material for storing hydrogen, an adsorbing material of biochemically noxious substances, an electrode material of a supercapacitor, a secondary cell and a fuel cell, and a catalyst carrier material.
