Abstract

Abstract:

To address the electromagnetic wave (EMW) pollution, developing efficient EMW-absorbing (EMWA) materials is still challenging. A bismuth-cobalt bimetallic organic framework was prepared by a polymer-assisted sol-gel method, and carbonized at high-temperature to obtain honeycomb-like BiCo@nitrogen-doped carbon (NC) composites. The carbonization temperature affects both the magnetic properties and electrical conductivity. With increasing temperature, the EMWA performance of BiCo@NC composites first increases and then decreases. At 750 ℃, the minimum reflection loss value is −47.29 dB at 2.40 mm, and the effective absorption bandwidth value is 6.72 GHz (11.28–18.00 GHz). The excellent EMWA performance is caused by the combined dielectric and magnetic loss synergy, multiple reflection and scattering, and impedance matching. Density functional theory calculations confirm that interfacial polarization enhances the EMWA performance, and radar cross-section calculations show the composites' practical application potential. This study offers a novel approach for high-efficiency carbon-based EMWA materials.

Key words: Electromagnetic wave absorption, Honeycomb structure, Polymer-assisted sol-gel method, Density functional theory
