The Novel Polarization Behaviors Induced by the Synergy of Fe Single Atoms and Multiscale Pores for High‐Performance Absorbers (Adv. Funct. Mater. 15/2026)

2D EMA Materials In their Research Article (10.1002/adfm.202526241), Pengfei Liu, Zhenhui Ma, and co-workers fabricate ultrathin nitrogen-doped carbon (NC) nanosheets integrated with controllable porous morphology, in which Fe particles and single atoms (SAs) are co-modified on the NC matrix. The synergy of Fe SAs and pore defects induce novel electron migration polarization behaviors, thereby promoting electromagnetic wave energy dissipation. This strategy effectively tackles electromagnetic interference and guarantees information security.
