AbstractThe intense requirement for bifunctional electromagnetic wave (EMW) absorbing materials is becoming the urgent focus and upgraded exploration for advanced application of absorbing EMW device in complex and extreme environments. Based on high dielectric loss capacity and superior chemistry inertness of graphite nanosheets, a two-dimensional (2D) graphite nanosheet decorated with graphite encapsulating soft-magnetic Ni3Fe nanocapsules was designed and exploited by introducing novel nitrogen catalyst in one-pot non-balance evaporating strategy. Through modulating the impedance matching and further optimal mass ratio, a minimum reflection loss (RL) of -35.8 dB at 7.35 GHz with an absorber thickness of 3.5 mm and a wide effective absorption bandwidth (EAB) of 5.5 GHz (RL <= -10 dB), which almost covered whole Ku-band, were realized with an absorber thickness of 2 mm. Combining the prominent EMW absorption, this 2D nanocomposite showed excellent comprehensive anti-corrosion ability to maintain the original microstructure in acidic, neutral and alkaline salty corrosion conditions. The successful exploration of 2D anticorrosive EMW absorber provides a significant insight for rational fabrication of futural bifunctional EMW absorbing devices in complex circumstances.
