With the popularization of 5G communication technology and the rapid development of electronic devices, electromagnetic interference (EMI) shielding materials are widely concerned. Conductive polymeric composites (CPCs) are usually used in EMI shielding due to their flexibility, corrosion resistance, processability and biocompatibility compared to metal-based EMI shielding materials. The demand for lightweight polymer composites in many fields such as aerospace and new energy vehicles is growing
