英文摘要	0 引言微波吸收剂是一类新型功能材料,主要用于吸收雷达波使目标难以被识别和发现,是隐身技术的重要组成部分,也是国内外军事领域内的高新技术之一.吸收剂的种类很多[1-3],其中多晶铁纤维是最近几年才提出的一种新型吸收剂,其直径在微米、亚微米、纳米量级,长度在几微米到几百微米范围变化,具有显著的形状各向异性,是最有发展前途的吸收剂之一.近几年来,国内外对多晶铁纤维的性能及应用研究报道较多[4、5],对多晶铁纤维的合成研究报道较少,而且介绍的十分简单.; The preparation and microwave-absorbing behavior of polycrystalline iron fibers modified with the thermal decomposition of carbonyl iron were studied in this paper. Through preparation of alpha-FeOOH fiber precursor, dehydration, reduction with hydrogen, modification with the thermal decomposition of carbonyl iron and passivation, polycrystalline iron fibers were yielded. a-FeOOH fiber precusor with optimum diameter and aspect ratio was made by using uniform seed crystal with optimum concentration and controlling the reaction time. Lacunas from procedure of dehydration and reduction were well modified with carbonyl iron. The sample with 1.95 mm thickness containting 60% by weight of modified polycrystalline iron fibers showed reflection loss over 10 dB within the frequency range of 8.5similar to14.6 GHz, and the maximum reflection loss was 21.8 dB at 11.3 GHz, while the sample of nonmodified polycrystalline iron fiber showed less reflection loss under same conditions.; http://gateway.webofknowledge.com/gateway/Gateway.cgi?GWVersion=2&SrcApp=PARTNER_APP&SrcAuth=LinksAMR&KeyUT=WOS:000220108300025&DestLinkType=FullRecord&DestApp=ALL_WOS&UsrCustomerID=8e1609b174ce4e31116a60747a720701 ; SCI(E); 中文核心期刊要目总览(PKU); 中国科技核心期刊(ISTIC); 中国科学引文数据库(CSCD); 6; 3; 358-362; 20
