SYNTHESIS METHOD OF CARBON NANOTUBES USING CARBON MATERIAL OBTAINED BY HEAT TREATMENT OF CELLULOSE FIBER AS SUPPORT, CARBON - CARBON NANOTUBE FILTER USING THEREOF

摘要

A synthesis method of carbide-carbon nanotubes using carbon obtained by heat treatment of cellulose fiber as a supporter is provided to grow carbon nanotubes showing excellent electric conductance, specific surface area and mechanical strength on carbides with high density. A synthesis method of carbide-carbon nanotubes using carbon obtained by heat treatment of cellulose fiber as a supporter comprises the following steps of: cleaning and drying cellulose fiber and inputting the cellulose fiber into a reactor to produce carbide in the presence of only hydrogen as ambient gas while controlling a temperature to a range of 500-1500°C; coating the produced carbide with nano-catalytic particles; inputting the prepared sample into a reaction furnace controlled within 500-700°C; and growing carbon nanotubes vertically with high density while supplying carbon sources.
