In the current contribution, copper-manganese bimetallic oxide nanoparticles attached to carbon nanotube surfaces have been created utilizing a straightforward method rather than complicated machinery. The employed sources of Cu and Mn were copper sulfate and potassium permanganate, which were combined with modified carbon nanotubes and thermally treated at 250, 350, and 450 °C, respectively. As the annealing temperature rises from 250 to 450 °C, the copper-manganese bimetallic oxide nanoparticles adhered to the surface of the carbon nanotubes gradually grow in size from 9 to 45 nm. XRD and FTIR methods were used to study structural characteristics. The existence of copper-manganese bimetallic oxide phases was established based on the results. The peak height and sharpness of the XRD data were also improved by increasing the annealing temperature, reflecting an improvement in the crystallinity. A broadband dielectric spectroscopy (BDS) was used to show how the applied frequency affected the dielectric characteristics.
