摘要	With the development of science and technology, there is a great demand for electromagnetic wave absorbing materials for both military and civilian purposes. Among them, carbonyl iron powder (CIP) has attracted a lot of attention due to its mature production system and good electromagnetic wave loss capability. However, the application of CIP is limited due to poor impedance matching, poor corrosion resistance, and poor oxidation resistance. Based on this, in this work, CIP and basalt fibers (BF) were used and flower-like ferrosoferric oxide (Fe3O4) was generated in situ on their surfaces by hydrothermal method. The results showed that the generation of Fe3O4 with the addition of BF greatly optimized the impedance matching of the CIP. The modified CIP had a minimum reflection loss of -51.09 GHz, corresponding to an effective absorption bandwidth (<-10 dB) of 6.16 GHz, fully covering the Ku-band with just a 1.5 mm coating thickness. Thanks to the protective effect of Fe3O4, the oxidation weight gain temperature of the modified CIP powder in air was increased from 240 degrees C to 500 degrees C, showing good thermal stability and oxidation resistance. In addition, the corrosion resistance of the coating was tested and analyzed using electrochemical impedance spectroscopy (EIS). The results showed that the impedance modulus of the coating at 0.01 Hz was enhanced by one order of magnitude from 10(6) Omegacm(2) to 10(7) Omegacm(2). Finally, the radar cross section (RCS) of the material was simulated using CTS software to further evaluate the wave absorption properties.
