abstract: Shielding against electromagnetic interference is critical in everyday life, particularly in communication, radar, radio astronomy, and medical equipment. The electromagnetic pollution caused by current electronic devices is increasing rapidly, and it is difficult to achieve a stable and efficient material that can play a significant role at higher frequencies. Due to their lightweight, chemical stability, and outstanding microwave absorbing properties with the inclusion of carbon materials, conductive polymer composites are the most promising EMI shielding materials for overcoming this problem. The PVDF@MMG polymer composite was formed in this research using an ultrasonication process. Fourier transform infrared, thermogravimetric analysis, field emission scanning electron microscopy, vibrating sample magnetometer, and vector network analyzer were used to investigate the physicochemical properties of the composite. At higher frequencies, the obtained polymer nanocomposite demonstrated remarkable shielding effectiveness of 51.74 dB with a low thickness of 3 mmat 12�18 GHz frequency range. The prepared nanocomposite has good EM stability across the frequency range, which is largely due to the filler's good dielectric and magnetic properties in the polymer matrix. © 2023 Elsevier Ltd
