SYNTHESIS AND APPLICATION OF FE-FILLED CARBON NANOTUBES COATED WITH FECO NANOPARTICLES

摘要

FeCo alloy nanoparticles were coated on Fe-filled carbon nanotubes by electroiess plating method. As-prepared samples were annealed at different temperatures. Relationship between electromagnetic properties and Fe/Co ratios of samples was established. Microwave absorbing performances of products were also measured. The results show that this novel nanocomposite has better microwave absorbing performance than Fe-filled carbon nanotubes, and is promising to be used as lightweight and wideband microwave absorber.
