Abstract
An electromagnetic shielding composite having nanotubes and a method of making the same are disclosed. According to one embodiment of the present invention, the composite for providing electromagnetic shielding includes a polymeric material and an effective amount of oriented nanotubes for EM shielding, the nanotubes being oriented when a shearing force is applied to the composite. According to another embodiment of the present invention, the method for making an electromagnetic shielding includes the steps of (1) providing a polymer with an amount of nanotubes, and (2) imparting a shearing force to the polymer and nanotubes to orient the nanotubes.
