摘 要: 本文阐述了电磁屏蔽材料重要性,并介绍电磁屏蔽材料的屏蔽原理,常见的电磁屏蔽材料种类及其特点,综述了高分子导电涂料、表面敷层型屏蔽材料、发泡金属类屏蔽材料近些年的国内外研究现状以及应用。鉴于北冶公司具有生产层状金属复合材料的丰富经验,提出可以通过优化层状金属结构及成分,开发新型电磁屏蔽用层状金属复合材料。 The significance of electromagnetic shielding material was explained. The shielding principle and the characteristics of general electromagnetic shielding materials were introduced. The progress and application of conductive polymers, surface-spreading materi- als and foamed metals were reviewed. Given the research experience on the laminar metal compositie, methods for improving structure of materials was provided, and exploit a new e- lectromagnetic shielding laminar metal composite.
