MAGNETIC NANOWIRES COMPRISING CARBON NANOFIBERS AND ITS PREPARATION METHOD

摘要

PURPOSE: A magnetic nanofiber containing a carbon nanofiber and a method for fabricating the same are provided to ensure high coercive force and to be used as a nanopowder for water treatment. CONSTITUTION: A method for nanofiber with a magnetic property comprises: a step of preparing a spinning solution containing a polymer, a magnetic nanoparticle or a magnetic nanoparticle precursor, a carbon nanofiber, a ceramic substance or a ceramic substance precursor, and a solvent; a step of electrospinning the spinning solution and preparing a nanofiber; a step of performing thermal treatment of the nanofiber under an air or oxygen atmosphere; and a step of performing thermal treatment of the nanofiber under a hydrogen atmosphere.
