METHOD OF PREPARING CARBON CAPSULES WITH NANO HOLLOW STRUCTURE AND CARBON NANO-CAPSULES PREPARED THEREFROM

摘要

PURPOSE: A method for preparing a carbon capsule having a nano-sized hollow structure and a carbon nanocapsule prepared by the method are provided, to obtain the carbon nanocapsule easily without an etching process. CONSTITUTION: The method comprises the steps of preparing a nano-sized spherical particle comprising a pyrolysis polymer at high temperature; coating the outer surface of the spherical particle with a carbonizing polymer at high temperature to prepare a core-shell composite comprising a pyrolysis polymer at high temperature as a core component and a carbonizing polymer at high temperature as a shell component; and heating the core-shell composite at a high temperature to pyrolyze the polymer of core component and carbonize the polymer of shell component. Preferably the pyrolysis polymer at high temperature is a linear polymer and the carbonizing polymer at high temperature is a crosslinked polymer.
