Abstract

The work aims to systematically summarize the recent advances of green EMI shielding conductive polymer composites (CPCs) to provide references for design and prepare absorption-dominated green EMI shielding CPCs. The significance of green EMI shielding materials and their similarities and differences with absorbing materials were clarified. The differences in performance testing principles and evaluation methods between them were expounded. The latest structural design strategies, forming processing methods and shielding performance regulation mechanisms of high-performance green EMI shielding CPCs were reviewed. The design and development directions of green EMI shielding CPCs were discussed and prospected. The development of the large-scale preparation method for construction of controllable electromagnetic gradient networks in high-performance polymer matrices is vital for the design of high-performance green EMI shielding CPCs, and it is expected that green EMI shielding CPCs with high efficiency and long-term durability, favorable environmental adaptability as well as multifunctionality and dynamic regulation of EM parameters will eventually be widely used in the EM compatibility and protection of the next-generation electronic devices.
