吸波涂层材料研究进展

在讨论吸波材料工作原理的基础上,综述了目前国内外吸波涂层材料的进展状况,较详细地介绍了铁氧体、纳米吸波材料、高温吸波材料、手性材料、等离子体吸波材料及磁性高分子微球等几种吸波涂层材料的最新研究现状,并分析了各种涂层材料的主要特点。传统铁氧体、金属微粉和陶瓷吸收剂由于密度大、吸收频段窄使其应用受到限制,手性材料、等离子体及磁性微球等新材料的探索研究将会成为吸波材料领域的发展方向。

Research progress in electromagnetic wave absorbing coating materials

In this paper, the international developments on electromagnetic wave absorbing coating materials are summarized on the basis of the discussion of the principles of wave absorption. Recent developments of absorbing coating, including ferrite materials, absorbing nano-materials, high temperature absorber, chiral material, plasma material and magnetic polymer microsphere, are introduced in details and their main characteristics are analyzed. The applications of the traditional ferrite materials, metal micro--powders and ceramic absorbers are limited because of their large densities and narrow absorbed frequency, the research on the chiral material, plasma material and magnetic microsphere will be the focus of the absorbing material.
