【摘要】 无线通信、雷达探测与射电天文技术推动了高频电磁频谱的应用,对盖微波、毫米波至太赫兹频段的超宽带电磁吸波材料产生了迫切需求。本研究提出一种基于静电自组装的新型策略,将MXene与CIP结合研制出磁-电协同的电磁吸波剂及相应的吸波涂层。该吸波涂层以2.0 mm厚度实现了2～1200 GHz的超宽带吸收,而进一步开发的4 mm厚可扩展结构性吸波体实现了7.95～4000 GHz的吸波能力,最大吸波效率达到了65 dB。该吸波涂层成功用于研制太赫兹吸波负载、宽带定标黑体、吸波型天线罩以及相控阵天线,展示出出色的与太赫兹组件和器件一体化集成能力。更多还原

【Abstract】 This study proposes a novel strategy based on electrostatic self-assembly,which combines MXene and CIP to develop magnetic-electric synergistic electromagnetic wave absorbers and corresponding absorbing coatings.The absorbing coating achieves ultra-wideband absorption of 2—1200 GHz with a thickness of 2.0 mm.Furthermore,the structured absorber(4 mm thick) realizes wave absorption capability in the range of 7.95—4000 GHz,with a maximum wave absorption efficiency of 65 dB.This wave-absorbing coating has been successfully applied to the development of terahertz waveguide loads,broadband calibrated blackbodies,wave-absorbing radomes,and phased array antennas,demonstrating excellent integration capability with terahertz components and devices.更多还原
