Effects of Copper Ferrite Nanoparticles on the Dielectric Properties of Cotton and Cotton–Polyester Mixture

The experiment investigated the dielectric properties of copper ferrite nanoparticle-doped cotton and cotton–polyester mixture and observed the higher dielectric permittivity of cotton–copper ferrite nanoparticles mixture than the cotton–polyester–copper ferrite nanoparticles mixture. This work describes the effects of copper ferrite nanoparticles on the dielectric properties of cotton and cotton–polyester mixture theoretically. The real and imaginary parts of the complex dielectric permittivity as function of temperature and concentration of copper ferrite nanoparticles are calculated. The decrease of dielectric permittivity of cotton–copper ferrite nanoparticles mixture and cotton–polyester–copper ferrite nanoparticles mixture with the increase of frequency has been observed. The comparison between theoretical and experimental results has been presented.
