CARBON NANO FIBER HAVING SKIN-CORE STRUCTURE, METHOD OF PREPARING SAME, AND PRODUCT CONTAINING SAID CARBON NANO FIBER

摘要

The present invention relates to a carbon nano fiber and more specifically to a carbon nano fiber that has a skin-core structure containing pitch and polyacrylonitrile (PAN), a method of preparing the same, and a product containing the carbon nano fiber. Because the carbon nano fiber of the present invention consists of PAN and pitch having diameters are 1 µm or less and characteristics different from each other by constituting a skin layer and/or a core layer, it has superior effects with that increase the diversity of functions of carbon nanofiber based on changes in composition.
