摘要

In this work, N-doped carbon fibers-Co₃O₄ (NCFs-Co₃O₄) composites are obtained through electrospinning, carbonization and oxidation processes. When the carbonization temperature is 800 °C, NCFs-Co₃O₄-800 shows efficient electromagnetic (EM) wave absorption properties. The maximum reflection loss (RL) reaches −57.6 dB at 9.04 GHz with a thickness of 3.9 mm. When the thickness is 3.0 mm, the maximum effective absorption bandwidth (EAB) reaches 6.64 GHz. The excellent performance is attributed to the abundant dielectric loss and magnetic loss effects, as well as good impedance matching. The results have positive significance for the research of carbon fiber-based composite absorbers.
