Multifunctional Hollow Carbon Microspheres Enable Superior Electromagnetic Wave Response and Corrosion Barrier

Electromagnetic (EM) wave absorbing materials with corrosion barrier exhibit immense potential in meeting the requirements of electronic defense technology in the complex marine environments, but still confront conflicts in disentangling the trade-off of multifunctional applications. Herein, hollow carbon microspheres (HCMs) that simultaneously possess superior EM wave absorption and anti-corrosion capability have been produced with the aid of self-sacrificing templates. During the pyrolysis, the reductive characteristic of Zn microspheres and thermal driving force promote magnetic domain evolution, which enables optimized hetero-interface resonance and strong magnetic interactions, facilitating a minimum…
