1. An electromagnetic shielding composite, comprising:
a polymer; and a carbon nanotube film structure disposed in the polymer; wherein the carbon nanotube film structure comprises a plurality of carbon nanotube films overlapped with each other to form a microporous structure defining a plurality of micropores, a diameter of the plurality of micropores is in a range from 0.5 micrometer to 1 micrometer, each of the plurality of carbon nanotube films comprises a plurality of carbon nanotubes substantially parallel with each other, and the polymer is coated on and covers entire surface of the carbon nanotube film structure, and the plurality of carbon nanotubes, in two adjacent layers of the plurality of carbon nanotube films, are aligned along different directions to form an angle, and the angle is 90°.
