Abstract

A groundbreaking approach is developed for the fabrication of directional macroporous WC_1−x/C foams, which frees the dependence on unidirectional freezing technique from the construction of directional macroporous carbon-based composites. The electrostatic interaction between ammonium metatungstate and protein makes in situ generated tungsten carbide (WC_1−x) nanoparticles well disperse on carbon flakes. The optimized foam exhibits exceptional electromagnetic absorption performance, achieving a remarkable minimum reflection loss of − 72.0 dB and an effective absorption bandwidth of 6.3 GHz.
