Directional Three‑Dimensional Macroporous Carbon Foams Decorated with WC1−x Nanoparticles Derived from Salting‑Out Protein Assemblies for Highly Effective Electromagnetic Absorption (IMAGE)
Caption
- A groundbreaking approach is developed for the fabrication of directional macroporous WC1−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 (WC1−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.
