Abstract

The demand for advanced radar absorbing materials (RAMs) in stealth technology and electromagnetic interference (EMI) shielding necessitates the development of lightweight, highly efficient polymer composites. This work investigates the frequency and temperature dependent dielectric properties of polyvinylidene fluoride (PVDF) and (G4/T10/PVDF). Utilizing the Debye relaxation model, a computational framework was developed using Maple 18 to simulate the dielectric constant and loss factor across the microwave frequency range of 0.50 to 21.0 GHz and temperatures from 20 °C to 100 °C. Results indicate that the dielectric constant of both materials exhibits typical dispersion behavior, decreasing with increasing frequency. However, the G4/T10/PVDF composite demonstrates significantly enhanced dielectric properties, with a dielectric constant of 42.0 compared to 20.5 for PVDF at 0.5 GHz. This behaviour exhibited by G4/T10/PVDF showed that even as the frequency and temperature become very high G4/T10/PVDF does not produce too much heat which may be the reason for reducing object detectability and electromagnetic interference (EMI) by radar.
