CARBON NANOTUBE (CNT)-ENHANCED PRECURSOR FOR CARBON FIBER PRODUCTION AND METHOD OF MAKING A CNT-ENHANCED CONTINUOUS LIGNIN FIBER

摘要

A precursor for carbon fiber production comprises a continuous lignin fiber including carbon nanotubes dispersed therein at a concentration of about 10 wt. % or less. A method of melt-spinning a continuous lignin fiber includes preparing a melt comprising molten lignin and a plurality of carbon nanotubes, and extruding the melt through a spinneret to form a continuous lignin fiber having the carbon nanotubes dispersed therein.
