Description

Polyvinylidene fluoride (PVDF)/multi-walled carbon nanotube (MWCNT) nanocomposites prepared by the solution casting method were examined for their electromagnetic interference shielding effectiveness (EMI-SE) in the frequency range of the X band (8.212.4 GHz). The study revealed that increasing MWCNT concentration significantly enhances the electrical conductivity, and EMI shielding performance of the PVDF matrix. Scanning electron microscopy (SEM) confirmed uniform dispersion of MWCNTs within the polymer matrix, contributing to the formation of an effective conductive network. As the MWCNT concentration increased, a transition from insulating to conductive behaviour was observed, with 6 wt% MWCNT composites achieving a conductivity of 0.058 S?cm?1 and an EMI-SE of 22.5 dB. These results demonstrate that PVDF/MWCNT nanocomposites are promising materials for lightweight and efficient EMI shielding applications. 2025 Informa UK Limited, trading as Taylor & Francis Group.
