摘要

Abstract

There has recently been a fundamental need to develop high efficiency microwave absorbers to reduce electro-magnet-ic pollution.It is often very difficult to obtain superior absorption with only one material,so we have explored composites using fillers of activated carbon derived from biological material(oleaster seeds)and resin(apricot tree gum)with Fe3O4 in a paraffin wax matrix to improve the dielectric properties and achieve a high specific surface area.A 1 mm thick layer of a Fe3O4+resin(FEOR),with the magnetic nanoparticles anchored to the gum,resulted in a reflection loss of-71.09 dB.We compared this with the results for composites using a filler of Fe3O4+activated carbon,and one with a three-component filler of Fe3O4+activated carbon+resin which had a very porous structure that had a direct effect on the surface polarization.However,the FEOR sample had near-ideal im-pedance matching,close to 1,which resulted in high absorption performance.In addition,the presence of defects improves mi-crowave attenuation by dipole polarization and charge carrier trapping.This work suggests the use of new types of biomaterials to in-crease microwave absorption.
