摘　　要：四针状氧化锌晶须(T-ZnOw)具有三维四针状结构,具有材料增强、抗静电、抗菌、吸波和吸声等特性,是一种非常有发展前途的多功能材料。利用四针状氧化锌晶须所具有的介电损耗特性,通过与羰基铁粉混杂,制备复合吸收剂。当涂层厚度为3mm,吸收剂和环氧树脂的质量比为2:1时,最大衰减达-24dB,对应频率为8.5GHz,<-10dB的带宽约为5.0GHz。Tetrapod-shaped zinc oxide whisker（T-ZnOw） has been discovered as the whisker that has the unique three-dimensional and tetrapod-shaped structure.It has the characteristics such as material strengthen,antistatic,antibiosis,sound and micro-wave absorption,and it is a multi-purpose materials with great potential development.In this paper,taken advantage of the electric loss characteristic which T-ZnOw has,mixed with the carbonyl iron powder to obtain the composite absorbent.The radar-wave absorbing coating were prepared with T-ZnOw and epoxy,when coat＇s thickness is 3.0mm,and the mass ratio between the absorbent and the resin 2：1,the most reflection attenuation amout of-24dB,corresponding frequency at 8.5GHz,and the band width that less than -10dB approximately 5.0GHz.
