CARBON NANOFIBER HAVING SKIN-CORE STRUCTURE, A MANUFACTURING METHOD THEREOF, AND PRODUCTS INCLUDING THE SAME, CAPABLE OF ADDING PROPERTIES TO ACCORDING TO USES OF THE CARBON NANOFIBER

摘要

PURPOSE: Carbon nanofiber having skin-core structure, a manufacturing method thereof, and products including the same are provided to reduce a diameter of fiber to one-tenths, and to improve spinning property of the nanofiber.;CONSTITUTION: Carbon nanofiber includes polyacrylonitrile(PAN) polymers, cores consisting of the copolymers and skin consisting of pitch surrounding the core. A solution in which PAN and the pitch are dissolved, is produced by dissolving the pitch and Pan in a solvent having the different boiling points. The pitch is a DMF insoluble part. The solubility of tetrahydrofuran is 95% or more.;COPYRIGHT KIPO 2010
