A METHOD OF ULTRA-FINE CARBON FIBERS AND ACTIVATED CARBON FIBERS BY ELECTROSPINNING FROM PHENOLIC-RESIN AND FIBER PRODUCED USING THE SAME

摘要

Phenol-group ultra-fine carbon fibers and activated carbon fibers and a manufacturing method thereof by using the electro-spinning are provided to add a curing agent into the phenol-group resin with the low viscosity, thereby manufacturing the fiber with a nano unit as a non-woven cloth state. In the first process, HMTA(Hexa Methylene Tetra Amine) of 10 to 15 % to the weight of the novolak phenol resin is added into the novolak phenol resin and dissolved into alcohol solvent so that the spinning solution is manufactured. In the second process, the spinning solution is previously heat-treated. In the third process, the ultra-fine phenol fiber web is formed through an electro spinning manner. In the fourth process, the thermosetting operation of the web is performed so that the ultra-fine phenol curing fiber is manufactured. In the fifth process, the phenol curing fiber is carbonated so that the ultra-fine carbon fiber is manufactured.
