Hyperbranched copper phthalocyanine decorated Fe3O4 microspheres with extraordinary microwave absorption properties?
RSC Advances Pub Date: 2014-12-08 DOI: 10.1039/C4RA12443J
Abstract
Novel hierarchical Fe3O4/hyperbranched copper phthalocyanines (Fe3O4–HBCuPc) composites were prepared via a simple solvent-thermal method. HBCuPc molecules were not only attached to the surface of Fe3O4 in the form of beads, but embedded in the interior. Importantly, the Fe3O4–HBCuPc composites exhibited enhanced microwave absorption properties after introducing the HBCuPc. The minimum reflection loss (RL) values could reach ?30.3 dB at 10.2 GHz and the bandwidth below ?10.0 dB increased up to 10.6 GHz, which covers the entire X-band and Ku-band (7.4–18.0 GHz). The introduction of HBCuPc can lead to improved efficient complementarities between the dielectric loss and the magnetic loss in the Fe3O4–HBCuPc, which can contribute to microwave absorption. Considering its lightweight, strong absorption and broad bandwidth, the as-prepared Fe3O4–HBCuPc can be applied as a new microwave absorber.
