Abstract
Polymer composites with carbon nanofillers are promising for electromagnetic shielding, with performance influenced by filler geometry, orientation, and temperature. Spherical carbon black enhances scattering, while anisotropic carbon nanotubes (CNTs) exhibit directional wave propagation and polarization. CNT orientation significantly affects the shielding efficiency, with the perpendicular alignment outperforming the parallel alignment. Temperature-dependent CNT polarization further underscores the need for thermal considerations in material design.
