电磁屏蔽橡胶复合材料的研究进展

Research Progress of Electromagnetic Shielding Rubber Composites

介绍电磁屏蔽橡胶复合材料及其所用胶种(天然橡胶、丁苯橡胶、三元乙丙橡胶、丁基橡胶和硅橡胶等)及电磁屏蔽填料[导电填料(金属和镀金属填料、导电炭黑、碳纤维、碳纳米管、石墨烯等)和吸波填料(铁氧体和羰基铁粉等)]的研究状况,并概述新型立体导电骨架结构电磁屏蔽复合材料的特征,指出电磁屏蔽橡胶复合材料的导电和吸波机理、结构以及橡胶与填料之间的界面作用等是今后的研究重点。

The research status of electromagnetic shielding rubber composites and their rubber types(natural rubber,styrene butadiene rubber,ethylene-propylene-diene rubber,butyl rubber and silicone rubber,etc.)and electromagnetic shielding fillers[conductive fillers(metallic and metal-plated fillers,conductive carbon black,carbon fibers,carbon nanotubes,graphene,etc.)and absorbing fillers(ferrite and carbonyl iron powder,etc.)]were introduced.The new electromagnetic shielding composites with threedimensional conductive framework structure were summarized.It was pointed out that the conductive and absorbing mechanism,structure and interface interaction between the rubber and filler of the electromagnetic shielding composites were the focus of future research.
