Infrared stealth cloth and infrared stealth clothes based on carbon nanotube

A piece of infrared stealth clothes, comprising:

• an infrared stealth cloth comprising:
• a cloth substrate;
• and
• an infrared light absorber located on the cloth substrate and comprising a carbon nanotube structure, wherein an absorptivity of the carbon nanotube structure in a wavelength range from about 2 μm to about 20 μm is greater than or equal to 98.975%;
• and the carbon nanotube structure comprises:
• a first drawn carbon nanotube film comprising a plurality of first carbon nanotubes joined end-to-end by van der Waals attractive force and substantially extending along a first direction;
• a second drawn carbon nanotube film comprising a plurality of second carbon nanotubes joined end-to-end by van der Waals attractive force and substantially extending along a second direction;
• and
• a third drawn carbon nanotube film comprising a plurality of third carbon nanotubes joined end-to-end by van der Waals attractive force and substantially extending along a third direction;
• wherein the first drawn carbon nanotube film, the second drawn carbon nanotube film, and the third drawn carbon nanotube film are stacked on each other;
• and the first direction and the second direction form an angle of about 42 degrees to about 48 degrees, and the first direction and the third direction form an angle of about 84 degrees to about 96 degrees.
