Phase specific dispersion of functional nanoparticles in soft nanocomposites resulting in enhanced electromagnetic screening ability dominated by absorption

Phase specific localisation of MWNTs and magnetic FeNi alloy particles resulted in significant electromagnetic (EM) shielding effectiveness in binary co-continuous blends of PVDF and SMA.

Electromagnetic screening in soft conducting composite-containing ferrites: the key role of size and shape anisotropy

We explored a facile bottom-up synthetic procedure to fabricate different shapes and size controlled Fe3O4 nanoparticles and showed the effect of shape anisotropy and size on the EM shielding properties.

Advantages of the Use of Metal Foams for Electromagnetic Shielding

Metal foams are very interesting materials in new emerging technologies as aeronautic, spatial research, auto-motion or heat exchanger, but there are other areas in which these materials could be advantageous. Here is a new proposal for using these materials in electromagnetic shielding. The goal is to demonstrate that, although having a smaller effective electrical conductivity than massive materials, it is possible to attain operative electromagnetic shielding with a reduction of mass and, in addition, to bring together in a single product a supplementary protection against vibrations, impact, noise, etc., as corresponds to the well-known properties of porous materials. In terms of the operating frequency, conductivity and thickness of the metallic foams the electromagnetic screening was calculated. It is shown how to guarantee a specified shielding the necessary thickness in porous materials with respect to massive metals obeys to a quadratic relation.
