Directional Three-Dimensional Macroporous Carbon Foams Decorated with WC_1-x Nanoparticles Derived from Salting-Out Protein Assemblies for Highly Effective Electromagnetic Absorption.

ABSTRACT: Directional three-dimensional carbon-based foams are emerging as highly attractive candidates for promising electromagnetic wave absorbing materials (EWAMs) thanks to their unique architecture, but their construction usually involves complex procedures and extremely depends on unidirectional freezing technique. Herein, we propose a groundbreaking approach that leverages the assemblies of salting-out protein induced by ammonium metatungstate (AM) as the precursor, and then acquire directional three-dimensional carbon-based foams through simple pyrolysis. The electrostatic interaction between AM and protein ensures well dispersion of WC_1-x nanoparticles on carbon frameworks. The content of WC_1-x nanoparticles can be rationally regulated by AM dosage, and it also affects
