Facile-synthesized carbonaceous photonic crystals/magnetic particle nanohybrids with heterostructure as an excellent microwave absorber

In this work, carbonaceous photonic crystals (CPCs) were obtained by the carbonization of butterfly wings, and the CPCs/magnetic particle (Fe3O4 and Fe) nanohybrids with heterostructure were synthesized by a facile single-mode microwave-assisted hydrothermal method. Scanning electron microscopy and...

Description
Summary:In this work, carbonaceous photonic crystals (CPCs) were obtained by the carbonization of butterfly wings, and the CPCs/magnetic particle (Fe3O4 and Fe) nanohybrids with heterostructure were synthesized by a facile single-mode microwave-assisted hydrothermal method. Scanning electron microscopy and transmission electron microscopy images indicated that CPCs exhibited a distinct structure of a periodic network interconnected by ridges and ribs with a highly smooth surface. The magnetic nanoparticles were also uniformly attached on the ridges and ribs of CPCs. The microwave absorption performances of CPCs/Fe3O4 and CPCs/Fe nanohybrids with heterostructure were investigated. The minimum reflection loss (RL) were −49.7 and −31.2 dB for CPCs/Fe3O4 and CPCs/Fe nanohybrids, respectively. The effective bandwidths (RL
