摘要: Abstract Fe3O4/dextran/SnO2 multilayer microspheres have been successfully designed and synthesized by solvothermal hydrothermal reactions. Dextran worked as a linker between Fe3O4 core SnO2 shell. It can not only prevent the oxidation of but also be carbonize to another absorber carbon black. The as-synthesized were about 320 nm in size well-defined shape. maximum reflection loss paraffin wax composites could reach 20.26 dB at 4.72 GHz, bandwidth with less than − 10 dB was 4.86 GHz 4 mm thickness. excellent microwave absorption properties attributed special structures effective complementarity dielectric magnetic loss.
