Synergistic enhancement of defect-induced polarization and built-in electric field effect in carbon hybrids towards efficient electromagnetic wave absorption

The incorporation of a built-in electric field (BIEF) in nanocomposites has been well-recognized as a mainstream approach for enhancing the interface polarization. Nevertheless, the effect of sole BIEF on the dielectric loss is insufficient, and its combination with other loss mechanisms is necessary to achieve optimized electromagnetic wave performances. Herein, the nano carbon hybrids with Cu–ZnO Schottky BIEF with abundant defects were designed and derived through an etching and ligand exchange process, which involved the conversion of CuZn-BTC into a bimetallic ZIF structure. The conversion process effectively controlled the morphologies and induced a significant density of defects in the derivatives,…
