摘要

To meet the demand of electromagnetic interference shielding, low-cost and easily available microwave absorbers are urgently required. A novel kind of covalently bonded GNPs-NH-PANI nanorod arrays modified by Fe₃O₄ nanoparticles (Fe₃O₄/GNPs-NH-PANI) with hierarchical structures was synthesized. The Fe₃O₄/GNPs-NH-PANI composite shows the maximum absorption of −40.31 dB at a thickness of 2.6 mm, and the corresponding bandwidth with effective attenuation (RL <−10 dB) is up to 9.62 GHz (7.85–17.47 GHz), suggesting that this cheap and available absorber is believed to be an optimal choice for the application of microwave attenuation.
