Electromagnetic shielding composite and method for making the same

A method for making an electromagnetic shielding composite, the method comprising the steps of:

• (a) providing an array of carbon nanotubes, a substrate, and a polymer;
• (b) drawing a carbon nanotube film from the array of carbon nanotubes, the carbon nanotube film comprising a plurality of carbon nanotubes joined end to end by van der Waals attractive forces;
• (c) covering at least one carbon nanotube film on the substrate to form a carbon nanotube film structure, extending directions of the carbon nanotubes in the carbon nanotube film structure are parallel with the substrate;
• and
• (d) combining the carbon nanotube film structure with the polymer to form an electromagnetic shielding composite.
