CONTINUOUS CARBON NANOTUBE COATING FILM MANUFACTURING APPARATUS AND A METHOD FOR MANUFACTURING A CARBON NANOTUBE COATING FILM USING THE SAME CAPABLE OF COATING A CARBON NANOTUBE-CONTAINING SOLUTION BASED ON A SPRAYING TECHNIQUE

摘要

PURPOSE: A continuous carbon nanotube coating film manufacturing apparatus and a method for manufacturing a carbon nanotube coating film using the same are provided to improve the stable quality of the carbon nanotube coating film based on a continuous manufacturing mode.;CONSTITUTION: A flexible base film is unwound using an unwinding unit(110) and transferred based on a roll-to-roll mode using a transferring unit(120). The transferred base film is surface-modified using a surface modifying unit(130) such that the surface tension of the base film is higher than the surface tension of a carbon nanotube-containing solution as much as in a range between 5 and 15 dyne/cm. The carbon nanotube-containing solution is coated on the base film using a coating unit(150) to form a carbon nanotube coating film. The content of carbon nanotube in the carbon nanotube-containing solution is between 0.1 and 10%. The carbon nanotube-containing solution is dried using a drying unit(160) to form a carbon nanotube coating film. The dried carbon nanotube coating film is rewound using a re-winding unit(190).;COPYRIGHT KIPO 2012
