摘要
随着信息时代的到来,电磁波的泄漏给人类健康带来了严重的危害,因此,高性能电磁防护材料的设计迫在眉睫。静电纺丝技术制备的复合纳米纤维具有质量轻、成本低、比表面积大、易加工和物理化学性能稳定等优点,是近年来高性能电磁屏蔽及吸波材料研究的热点。本文首先介绍了电磁屏蔽及吸波的基本原理,并结合国内外研究现状,将市场上应用广泛的电磁屏蔽及吸波材料系统的分成了金属及金属氧化物、碳材料、导电聚合物和过渡金属碳化物4类,并进行了详细了介绍。同时,综述了各种填料对电磁屏蔽及吸波性能的影响及目前正面临的问题。
With the advent of the information age, the leakage of electromagnetic waves has brought serious harm to human health, therefore, the design of high-performance electromagnetic protection materials is imminent. The composite nanofibers prepared by electrostatic spinning technology have the advantages of lightweight, low cost,large specific surface area, easy processing, and stable physicochemical properties, which are the hot spots for the research of high-performance electromagnetic shielding and absorbing materials in recent years. This article firstly introduces the basic principles of electromagnetic shielding and absorbing, and combines the current situation of domestic and foreign research, and systematically classifies the widely used electromagnetic shielding and absorbing materials in the market into four categories: Metals and metal oxides, carbon materials, conductive polymers,and transition metal carbides. Meanwhile, the influence of filler on electromagnetic shielding and absorbing performance and the current problems being faced are overviewed.
