Fabrication and microwave absorbing properties of Li0.35Zn0.3Fe2.35O4 micro-belts/nickel-coated carbon fibers composites

The Li0.35Zn0.3Fe2.35O4 micro-belts were prepared by cotton template for the first time. The nickel-coated carbon fibers were obtained by the electroless plating method. The formation mechanism of the ferrite micro-belt was studied. The microwave absorption properties of the two layers absorbers containing Li0.35Zn0.3Fe2.35O4 micro-belts and nickel-coated carbon fibers composites were investigated in the frequency range of 30–6000 MHz. The absorbers of the Li0.35Zn0.3Fe2.35O4 micro-belts/nickel-coated carbon fibers composites have much better microwave absorption properties than the nickel-coated carbon fibers absorbers, and the microwave absorption properties of the composites are influenced by the content of the absorber.
