Ultralight activated carbon/polyimide foam with heterogeneous interfaces for improved thermal stability, mechanical properties, and microwave absorption

The activated carbon (AC) has been widely used in the field of electromagnetic protection because of its porous, hollow microstructure and excellent electrical conductivity. In this paper, AC was prepared through KOH activation process. The ACs/polyimide foam (PIF) composite was prepared in situ dur...
