导电聚苯胺/羰基铁粉复合吸收效能的研究
Conductive Polyaniline/Iron Carbonyl Powder Composite Material
for Wave Absorbing Property
摘要 利用软磁金属粉末羰基铁粉的良好电磁吸收特性,加入不等量的导电聚苯胺,制备成导电聚苯胺/羰基铁粉复合材料。在1.8 mm厚的涂层中,随导电聚苯胺含量的增加,其吸波效能得到显著改善。分析表明,导电聚苯胺/羰基铁粉有利于发展成为轻质、宽频、强吸收的优良吸波材料。

Abstract The conductive polyaniline/ iron carbonyl powder composite material was
prepared based on the utility of the good electromagnetic wave absorbing property of
soft magnetic metal powder-iron carbonyl powder and the addition of various amount
of conductive polyaniline.For a dope of 1.8 mm,with the increase of the amount of
conductive polyaniline,its wave absorbing property got significantly improved.The
analysis demonstrates that conductive polyaniline/iron carbonyl powder,due to its
composite wave absorbing property,is inclined to become an excellent wave absorbing
material with light weight,wide frequency and strong wave absorption capability.
Keywords wave absorbing material;wave absorbing property;conductive polyaniline;
