Abstract:
1. A method for making carbon nanotube slurry, the method comprising: providing a carbon nanotube film, wherein the carbon nanotube film comprises a plurality of carbon nanotubes oriented along substantially a first direction; cutting the carbon nanotube film along a second direction to form at least one carbon nanotube belt, wherein the second direction is substantially perpendicular to the first direction, and the at least one carbon nanotube belt has a uniform width; mixing an inorganic binder, an organic carrier and the at least one carbon nanotube belt in an organic solvent to form a mixture; adding a filler in the mixture, wherein a weight percentage of the carbon nanotubes in the carbon nanotube slurry ranges from about 2% to about 5%, a weight percentage of the inorganic binder ranges from about 2% to about 5%, a weight percentage of the filler ranges from about 3% to about 6%, and a weight percentage of the organic carrier ranges from about 84% to about 93%; and removing the organic solvent from the mixture, wherein at least one carbon nanotube belt is formed by cutting the carbon nanotube by a laser having a power ranging from 1 watt to 100 watts.
