Abstract: In order to avoid using polymer as basis materials and further expand the application of carbon-based absorbing materials in space or simulated space environments, a new idea for preparing pyrolytic carbon foam absorbing materials by the precast body method combined with pyrolysis process was proposed in this work. A series of pyrolytic carbon foams were prepared at different target pyrolysis temperatures ranging from 400 ℃ to 1 500 ℃. Through the analysis of Fourier infrared spectrum (FTIR), thermogravimetric and differential scanning calorimetry(TG-DSC), X-ray diffraction (XRD) and electrochemistry of the pyrolytic carbon foam materials at different temperatures, it is confirmed that the pyrolytic carbon foam is a semiconductor material. The threshold, conjugation and site resistance effects caused by the pyrolytic residual functional groups and their disordered region inhibit π-electron off-domain mobility and control the carrier concentration, which in turn affect the electromagnetic properties of pyrolytic carbon foam materials. The electromagnetic parameters of carbon foam materials at different pyrolytic temperatures show that the pyrolytic carbon foam materials at 600 ℃ to 700 ℃ are suitable for use as absorbing materials.
