摘要

FeNi_3/indium tin oxide (ITO) composite nanoparticles were synthesized by a self-catalyzed reduction method and a sol-gel process. The dependence of the content of ITO phase with the mole ratios of ln:Sn of different sols was investigated. The relation between the electrical conductivity, infrared emissivity of FeNi_3/ITO composite nanoparticles and the content of ITO phase was discussed. Electromagnetic wave absorption (EMA) performance of products was evaluated by using transmission line theory. It was found that EMA performance including the intensity and the location of effective band is significantly dependent on the content of ITO phase. The low infrared emissivity and superior EMA performance of FeNi_3/ITO composite nanoparticles can be both achieved when the mole ratio of In:Sn in sol is 9:1.
