Directional Three‑Dimensional Macroporous Carbon Foams Decorated with WC1−x Nanoparticles Derived from Salting‑Out Protein Assemblies for Highly Effective Electromagnetic Absorption
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 rem Credit: Yongzheng Chen, Lixue Gai, Bo Hu, Yan Wang, Yanyi Chen, Xijiang Han, Ping Xu, Yunchen Du*.

As electromagnetic (EM) pollution intensifies worldwide, developing high-performance EM wave absorbing materials (EWAMs) becomes critical. Researchers from Harbin Institute of Technology, led by Prof. Yunchen Du, have proposed a groundbreaking strategy to fabricate directional 3D macroporous carbon foams decorated with WC 1-x nanoparticles via salting-out protein assemblies from egg white. This work pioneers a simple yet scalable route to construct anisotropic carbon-based EWAMs without relying on conventional unidirectional freezing techniques.
