Lately, silicone rubber because of the desirable permittivity on the one hand and various applications in the implants, membranes, Solar cells, sensors, Semiconductor devices, high frequency devices, photothermal therapy methods, acoustic metamaterials, and insulator materials on the other hand has attracted considerable attentions. In this research, CuCr2O4 nanoparticles were prepared according to the sol-gel method and then were identified by Fourier transform infrared (FT-IR), X-ray powder diffraction (XRD), field emission scanning electron microscopy (FE-SEM), and vibrating sample magnetometer (VSM). Results showed that monophase crystal structure with identical morphology of CuCr2O4 nanoparticles has been synthesized. Finally, CuCr2O4 nanoparticles and silicone rubber were composited and then microwave absorbing properties of the CuCr2O4/silicone rubber nanocomposite were investigated by vector network analyzer (VNA) exhibiting 48.56 dB microwave attenuation of the CuCr2O4/silicone rubber nanocomposite with 2.6 mm thickness at 10.9 GHz frequency and more than 92.99% microwave absorption in the x-band frequency.
