Abstract:
1. A method for making carbon nanotube slurry, the method comprising: providing a carbon nanotube array on a substrate, the carbon nanotube array comprising a plurality of carbon nanotubes; trimming the carbon nanotube array by a laser to obtain a trimmed carbon nanotube array, wherein the entire carbon nanotube array on the substrate is trimmed, and the trimmed carbon nanotube array has a plurality of trimmed carbon nanotubes having substantially uniform lengths, wherein a power density of the laser is larger than or equal to 12×10 removing the trimmed carbon nanotube array from the substrate to obtain the trimmed carbon nanotubes having the substantially uniform lengths; and mixing the trimmed carbon nanotubes with an inorganic binder and an organic carrier to obtain a carbon nanotube slurry wherein the step of trimming the carbon nanotube array by the laser comprises:
