摘要

一种突破性的方法被开发用于制造定向大孔WC1 - x/C泡沫，它从定向大孔碳基复合材料的构建中解放了对单向冷冻技术的依赖。偏钨酸铵与蛋白质之间的静电相互作用使得原位生成的碳化钨纳米颗粒（WC1−x）在碳片上分散良好。优化后的泡沫具有优异的电磁吸收性能，最小反射损耗为- 72.0 dB，有效吸收带宽为6.3 GHz。

Directional Three-Dimensional Macroporous Carbon Foams Decorated with WC1−x Nanoparticles Derived from Salting-Out Protein Assemblies for Highly Effective Electromagnetic Absorption

Highlights

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.

期刊介绍： Nano-Micro Letters is a peer-reviewed, international, interdisciplinary, and open-access journal published under the SpringerOpen brand. Nano-Micro Letters focuses on the science, experiments, engineering, technologies, and applications of nano- or microscale structures and systems in various fields such as physics, chemistry, biology, material science, and pharmacy.It also explores the expanding interfaces between these fields. Nano-Micro Letters particularly emphasizes the bottom-up approach in the length scale from nano to micro. This approach is crucial for achieving industrial applications in nanotechnology, as it involves the assembly, modification, and control of nanostructures on a microscale.
