Synergistic Polarization Relaxation in Multi‐Level Hybridization and Preferred Orientation Strategies for Electromagnetic Wave Absorption

ABSTRACT Achieving precise control over the electromagnetic response of materials across multiple length scales from atomic to mesoscopic via multi‐level hybridization and preferred orientation strategies remains a central challenge in the development of high‐performance electromagnetic wave (EMW) absorbers. This work successfully prepared a CoSe 2 /Ni 3 Se 2 /CeSe 1.9 /CNFs (CNCS) composite with a multi‐level hybrid structure via a multi‐step hydrothermal‐selenization method. The core innovatio
