Abstract
Shielding materials are fabricated from a new three-layered particle having a core, a metal layer, and a conductive polymer layer. The new particles are blended into a polymer matrix and processed in the absence or under the influence of a magnetic field to form single-layered coatings and freestanding films and sheets. The magnetically processed materials yield a conductive network of particles rather than discrete particles randomly disposed within the polymeric medium.
