摘要

The application of semiconductor materials was limited as electromagnetic absorption materials, due to the unstable absorption performance caused by the temperature sensitivity. In this work, a structurally controllable ceramic heterojunction was developed by assembling structural units of SiC nanowires (SiCnws) and Ba0.75Sr0.25Al2Si2O8 (BSAS). Benefiting from the optimization of the energy gap and the construction of heterogeneous interfaces, the ceramic heterojunction can achieve stable electromagnetic absorption from room temperature to 600 °C, the effective absorption bandwidth is almost unchanged. And the minimum reflection loss value reached -63.6 dB at 600 °C. Meanwhile, the SiCnws/BSAS ceramic heterojunction shows stable electromagnetic absorption performance in various simulated outdoor environments, including acid rain, seawater, high temperature and water vapor corrosion. This result provides a fire-new idea to realize the environmental adaptability of electromagnetic absorption materials and largely broadens its application prospect.
