The increasing prevalence of electronic devices and 5G technology has exacerbated electromagnetic wave (EMW) pollution, necessitating effective countermeasures. Microwave-absorbing materials (MAM) offer promising solutions to address this issue. Owing its exceptional dielectric properties, low density, thermal conductivity, chemical stability, boron nitride (BN) is a suitable candidate for MAM development. This study investigates the optimization BN microwave absorption performance through nanocomposite fabrication. composite been engineered with enhanced polarization improved interfacial interactions by incorporating into an epoxy resin matrix modified silane-functionalized cardanol. resulting material exhibited superior surface roughness hydrophobicity. optimal formulation demonstrated outstanding achieving reflection loss −23 dB at 12.4 GHz thickness only 10 mm. Furthermore, displayed mechanical damping value 0.85. These results suggest that synergistic effect impedance matching multiple mechanisms within structure contributes performance.
