Photo-catalytic activity of cobalt ferrite/polyaniline magnetic nanocomposite was investigated for degradation of four Azo dyes (acid black, acid brown, acid violet and Congo red). For this purpose at the first step CoFe₂O₄ nanoparticles was synthesized via a fast and simple precipitation method. CoFe₂O₄/polyaniline nanocomposites were then prepared using simple polymerization method of aniline monomer. The absorption property of radio waves in the microwaves band by cobalt ferrite–polyaniline nanocomposites was studied as well. The results introduce the cobalt ferrite–polyaniline nanocomposites as a radar absorbing coatings. The crystal structure was studied using X-ray diffraction and particle size was determined by scanning electron microscopy. Vibrating sample magnetometer was used for magnetic analysis and by applying Fourier transform infrared spectrometer, the purity of the material was also determined. Photocatalytic activity of nanocomposites was investigated by analyzing UV–Vis spectrograph. In order to examine the radar absorption properties of cobalt ferrite/polyaniline nanocomposites, the absorption of radio waves in the range of 8–12 GHz was measured. These samples have absorption peaks around bandwidth 12–12.5 GHz and absorption amounts were about 70 percent and decrease reflecting was around − 6.4 dB frequency ranges.
