Complex dielectric permittivity of composites based on dielectric matrixes with inclusions of carbon nanotubes

Complex dielectric permittivity of composites based on two-component epoxy adhesive with different volume concentration of inclusions of multilayer carbon nanotubes and particles of fine-dispersed graphite was determined from the transmission spectra of the microwave radiation interacting with the sample under investigation. Complex dielectric permittivity of multilayer carbon nanotubes and particles of fine-dispersed graphite was determined as a result of reverse problem solving with utilization of the dependency of complex dielectric permittivity of composites on the inclusions volume fraction. It was shown that in creating composites based on dielectric matrixes with inclusions of particles of fine-dispersed graphite and carbon nanotubes the last ones provides the greater of the real part of dielectric permittivity and the lesser of the imaginary part of dielectric permittivity.
