Abstract

Present work reports the fabrication of EMI shielding composites consisting of multi-walled carbon nanotubes (MWNTs) and graphite uniformly dispersed in an insulating polymer matrix i.e. polyvinylidene fluoride (PVDF). The EMI shielding is measured in the X-band frequency range (8–12 GHz) for all the composites. Absorption and reflection radiations are seen to be increasing with increasing the graphite and MWCNT level in the composite and a high EMI shielding effectiveness (SE) value of 14.64 dB has been achieved. The results are promising for the development of a novel, low cost, light weight, and flexible EMI shielding material.
