Self‑Sensing NiFe@N‑doped Carbon Aerogel: Integrating Excellent Radar Stealth, Inherent Structural Health Monitoring, Thermal Management, and Flame Retardancy

Caption

  • The biomimetic honeycomb-like porous magnetic NiFe@N-doped carbon aerogel (NFNCA) was efficiently fabricated through chemical cross-linking, in situ growth, unidirectional freeze-drying, and pyrolysis carbonization.
  • The synergistic effect arising from the 3D conductive networking structure, diverse heterogeneous interfaces, magnetic/dielectric multi-component, and multiple loss pathways of NFNCA endowed this carbon aerogel with outstanding impedance matching and electromagnetic wave attenuation performance.
  • The NFNCA featured excellent microwave attenuation, real-time monitoring of structural integrity, infrared thermal stealth, thermal management, and flame retardancy capabilities.
