specific Embodiment

[0027] 1. Preparation of carbon nanotube network (bucky paper):

[0028] Single-wall or multi-wall carbon nanotubes can be used. The single-wall or multi-wall carbon nanotubes used in this embodiment have a diameter of 8-15 nm, an average diameter of 10 nm, and a length of 1-100 μm, with an average length of about 10 μm. First, the carbon nanotubes are moderately mechanically ground, and then ultrasonically dispersed in ethanol containing a certain surfactant. The dispersed solution is vacuum filtered under the filter membrane, and the solution forms a film on the surface of the filter membrane, and then the carbon nanotubes are The tube paper is separated from the filter membrane, the dispersant is washed off with water, and dried in an oven at 60°C to obtain the carbon nanotube bucky paper. The amount of carbon nanotubes can be flexibly adjusted according to needs, so as to prepare carbon nanotube bucky paper with a thickness of 0.02 mm to 1 mm.
