| Research Abstract |
The purpose of this research was to increase microwave absorption properties of amorphous Fe-B/polymer composites prepared using surface coating or cross link reaction. The following results were obtained. 1) Amorphous Fe-B sub-micron particles were obtained by reduction method and the polymer composites showed high permeability, noise suppression, and microwave absorption properties. 2) The mixing of AFBS or NiZn ferrite nano-particles with AFBS particles is effective for improving properties of polymer composites. 3) Ferrite plating is one of promising methods for the enhancement of resistivity of AFBS. This method has a possibility for increasing microwave absorption properties.
