THE MANUFACTURING METHOD FOR CARBON NANOTUBES ADSORBED GLASS FIBERS

摘要

PURPOSE: A method for manufacturing a carbon nanotube-adsorbed glass fiber is provided to improve the strength of conductive glass fiber reinforced plastics intermediate. CONSTITUTION: A method for manufacturing a carbon nanotube-adsorbed glass fiber comprises the steps of removing the impurities of a multi-walled carbon nanotube by purification; dispersing the purified carbon nanotube in an aqueous solution, an alcohol and other organic solvent to prepare a dispersion; and adsorbing the carbon nanotube on the surface of a glass fiber by infiltration. The purification is carried out by using a mixture of sulfuric acid and nitric acid in a ratio of 3:1.
