Abstract
ABSTRACT Accurately controlling the particle state and clarifying the relationship between particle structure and electromagnetic wave (EMW) are crucial for the development of high‐performance EMW absorbers, which are essential to address the challenges of electromagnetic pollution and stealth technology. However, achieving both high‐temperature resistance and low‐frequency response in ceramic‐based absorbers remains a significant challenge. Herein, we propose a metal nanoparticle diffusion‐dissolution mechanism through an atomic‐level engineering strategy to effectively control the evolution of Fe nanoparticles into Fe single atoms within SiOC ceramic fibers. By precisely optimizing the nitrogen source, the…
