In the present work, electromagnetic interference shielding properties of polymer composites with dispersed cup-stacked carbon nanotubes, graphite nanoparticles and carbon black were investigated. The polymer composites with carbon nanoparticles content from 1 to 5 w% were successfully prepared by the coagulation method, and composite sheets with thickness from 0.25 to 0.77 mm were formed by the hot press technique. The electromagnetic interference shielding efficiency measured in the frequency range of 8.2~12.4 GHz (X-band) of cup-stacked carbon nanotubes/polymer composite was considerably higher than that of carbon black and graphite nanoparticles polymer composites at the same contents of carbon nanoparticles, and contribution of absorption to the shielding efficiency was found to be higher than that of reflection.

Extensive Growth

The extensive growth of telecommunication and electronic devices has led to significant concerns regarding electromagnetic (EM) radiations. Thus, the effect of EM radiations can be reduced by using highly efficient shielding materials. This review aimed to explore the electromagnetic interference (EMI) shielding materials based on polyvinylidene fluoride (PVDF), polyurethane (PU), and polyaniline (PANI) composites. It was found that the composites based on PVDF, PU, and PANI polymers have attracted considerable interest and highly efficient for EMI shielding due to their remarkable properties like lightweight, thermal stability, processing benefits, cheap, tremendous flexibility, and excellent resistance to corrosion. Hence, the PVDF-, PU-, and PANI-based composites are efficient EMI shielding materials.
