Electromagnetic wave absorption materials inevitably encounter corrosive conditions during service, making corrosion-resistant design essential for their practical deployment.
Researchers from China’s Northwestern Polytechnical University have developed a magnetic graphene composite aerogel (reduced graphene oxide (rGO)/ porous hollow Ni/C microspheres (PHNiC)). The new aerogel reportedly demonstrates excellent impedance matching and electromagnetic attenuation, achieving a minimum reflection loss of −51.3 dB at a thickness of 2.5 mm and a broad effective absorption bandwidth of 6.64 GHz.
