YWYan WangXZXiang ZhouHGHu Gu

Key Points

  • The research aims to create a new type of wave-absorbing material using starch-based carbon aerogels doped with FeCoNi.
  • Synthesis of starch-based carbon aerogels doped with FeCoNi
  • Characterization of magnetic and dielectric properties
  • Measurement of microwave absorption performance
  • Achieved a minimum reflection loss (RL min) of -60.89 dB
  • Demonstrated an effective absorption bandwidth (EAB) of 7.91 GHz
  • Showed enhanced microwave absorption due to magnetic–dielectric synergy

Abstract

FeCoNi-doped starch carbon aerogels achieve superior microwave absorption (RL min = −60.89 dB, EAB = 7.91 GHz) via magnetic–dielectric synergy, offering a green strategy for efficient electromagnetic attenuation.
