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.

由于这些材料的科学和技术商业意义，导电杂化纳米填料已成为最近研究兴趣的前沿。在这里，我们报告通过使用溶液共混方法，制备了填充有功能化碳纳米纤维（FCNF）和纳米结构的科琴炭黑（K-CB）杂化纳米填料的氯化聚乙烯（CPE）纳米复合材料。在CPE基质中掺入杂化纳米填料导致热，机械和电性能的大幅提高。正确分配混合纳米填料可实现2.2×10 ^-2的出色电导率 在X波段频率中，混合纳米填料的含量为15 wt％时，S / cm和卓越的电磁干扰（EMI）屏蔽性能（33 dB）。此外，我们针对暴露于热空气老化处理后的导电性和屏蔽性能提供了有用的性能。这项工作的新颖之处在于两种纳米填料的结合所产生的独特的协同作用，这种填料可作为出色的EMI屏蔽材料，是对抗EM污染的有力候选者。
