Abstract

Conductive hybrid nanofillers have become front facet of the recent research interest because of the scientific and techno-commercial significance of these materials. Herein, we report the fabrication of chlorinated polyethylene (CPE) nanocomposites filled with hybrid nanofiller of functionalized carbon nanofiber (FCNF) and nano-structured ketjen carbon black (K-CB) by using solution blending approach. Incorporation of hybrid nanofiller in CPE matrix led to a drastic enhancement in thermal, mechanical, and electrical properties. Proper distribution of hybrid nanofiller leads excellent electrical conductivity of 2.2 × 10⁻² S/cm and superior electromagnetic interference (EMI) shielding performance (33 dB) at 15 wt% hybrid nanofiller content in X-band frequency. Further, we addressed the serviceable performance in electrical conductivities and shileding performances after exposed to thermal-air ageing treatment. The novelty of this present work lies in the unique synergism arising from the combination of two nanofillers, which serves as outstanding EMI shield material as a capable candidate against EM pollutions.
