Electromagnetic properties of carbonyl iron/polyaniline microtubules

The polyaniline microtubules were prepared by using an in-situ doping method. The polyaniline microtubules with the dielectric loss properties were composed with the carbonyl iron with the magnetic loss properties. The electromagnetic properties of the composite were studied. The results show that the electromagnetic parameter can be adjusted through changing the mass ratio of carbonyl iron to polyaniline microtubules in the composites when the mass ratio of paraffin wax to the composites of carbonyl iron/polyaniline microtubules is constant at 1:1.
