Ferrite Load Effects on the Mechanical and Electromagnetic Properties of NiZn Ferrite Powders-epoxy Resin Coatings

摘要

This study investigates the ferrite load effects on the thermo-mechanical and electromagnetic properties of NiZn ferrite powder- epoxy resin coatings. It was observed that the Young's modulus and glass transition temperature of the composites decreased as the ferrite load increased from 30 to 50wt% and increased as the ferrite load was further increased above 70wt%. The dielectric constants and initial permeability both increased with increasing ferrite load. The thermal decomposition offset temperature for composites with ferrite loading was shifted toward higher temperatures compared to the neat epoxy.
