A PRE-TREATMENT METHOD OF CARBON NANOTUBE FOR CARBON NANOTUBE/POLYMER COMPOSITES, A MANUFACTURING METHOD FOR CARBON NANOTUBE/POLYMENR COMPOSITES, AND CARBON NANOTUBE/POLYMENR COMPOSITES USING THE PRETREATMENT METHOD OF CARBON NANOTUE

摘要

A method of pre-treating a carbon nanotube for a polymer/carbon nanotube composite is provided to use no acid injuring a surface of the carbon nanotube, to improve dispersibility of the carbon nanotube and to disperse the carbon nanotube uniformly in a polymer matrix. A method of pre-treating a carbon nanotube for a polymer/carbon nanotube composite comprises steps of: mixing the carbon nanotube into a solvent; and processing the carbon nanotube in the solvent with an ultrasonic wave at a frequency range of 20,000Hz to 60,000Hz and for 30 to 180 minutes and obtaining a carbon nanotube dispersion solution.
