Abstract

Technologies based on microwave absorption are based on science of absorber materials
in this frequency range. The nature of microwave is an alternating electrical and
magnetic field that could be naturally absorbed in transmission through materials with nonzero
conductivity or imaginary part of permittivity (dielectric loss) and nonzero imaginary
part of magnetic permeability (magnetic loss). Meanwhile, microwave absorbing polymer
composites due to their light weight, low fabrication cost, and high performance have
significant importance. Polymer matrix of these composites are generally nonconductive
materials that are host for microwave absorbing materials such as carbon nanotube, ferrite,
and titanium dioxide, and so conductivity enhancement of polymer matrix could be effective
on improvement of absorption mechanism especially in nonconductive magnetic absorbers.
In this regard, polyaniline as a conductive polymer, has important role in improvement
of quality of absorbing composites in microwave range. Also, improvement of various
characteristics of polyaniline has strong dependence on properties of other components
and especially on synthesis method. Therefore, especial consideration on various kinds,
components, and synthesis methods of such composites and key role of polyaniline in
their properties is critical for researchers in the field. In this paper, after introducing the
mechanism of electromagnetic wave absorption, we introduce different kinds of composites
including polyaniline with other organic and inorganic materials, synthesis methods, and
properties related to design of microwave absorbers.
