Abstract

Since electromagnetic pollution is detrimental to human health and the environment, numerous efforts have been successively made to achieve excellent electromagnetic interference shielding effectiveness (EMI SE) via designing the hierarchical structures for electromagnetic interference (EMI) shielding polymer composites. Among the plentiful structures, the asymmetric structures are currently a hot spot, principally categorizing into multi-layered, porous, fibrous, and segregated asymmetric structures, which endows the high EMI shielding performance for polymer composites incorporated with magnetic, conductive, and/or dielectric micro/nano-fillers, due to the “absorption-reflection-reabsorption” shielding mechanism. Therefore, this review provides the retrospection and summary of the efforts with respect to abundant asymmetric structures and multifunctional micro/nano-fillers for enhancing EMI shielding properties, which is conducive to the booming development of polymeric EMI shielding materials for the promising prospect in modern electronics and 5-generation (5G) technology.

用于出色电磁干扰屏蔽的不对称结构复合材料的最新进展：综述

由于电磁污染不利于人类健康和环境，人们一直在努力通过设计电磁干扰（EMI）屏蔽聚合物复合材料的分层结构来实现优异的电磁干扰屏蔽效果（EMI SE）。在众多结构中，非对称结构是目前的热点，主要分为多层结构、多孔结构、纤维结构和隔离式非对称结构，由于其 "吸收-反射-吸收 "的屏蔽机理，加入磁性、导电和/或介电微型/纳米填料的聚合物复合材料具有很高的电磁干扰屏蔽性能。因此，本综述对丰富的非对称结构和多功能微/纳米填料在增强电磁干扰屏蔽性能方面所做的努力进行了回顾和总结，这有利于聚合物电磁干扰屏蔽材料的蓬勃发展，在现代电子和五代（5G）技术中具有广阔的前景。

期刊介绍： Chinese Journal of Polymer Science (CJPS) is a monthly journal published in English and sponsored by the Chinese Chemical Society and the Institute of Chemistry, Chinese Academy of Sciences. CJPS is edited by a distinguished Editorial Board headed by Professor Qi-Feng Zhou and supported by an International Advisory Board in which many famous active polymer scientists all over the world are included. The journal was first published in 1983 under the title Polymer Communications and has the current name since 1985. CJPS is a peer-reviewed journal dedicated to the timely publication of original research ideas and results in the field of polymer science. The issues may carry regular papers, rapid communications and notes as well as feature articles. As a leading polymer journal in China published in English, CJPS reflects the new achievements obtained in various laboratories of China, CJPS also includes papers submitted by scientists of different countries and regions outside of China, reflecting the international nature of the journal.
