Abstract
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 â40.31â¯dB at a thickness of 2.6â¯mm, and the corresponding bandwidth with effective attenuation (RL <â10â¯dB) is up to 9.62â¯GHz (7.85-17.47â¯GHz), suggesting that this cheap and available absorber is believed to be an optimal choice for the application of microwave attenuation.
