Abstract
A novel magnetic nanocomposite of carbonized bacterial cellulose (CBC) modified by CoFe2O4 nanocrystals with different contents were synthesized successfully using an effective solvothermal method. Scanning electron microscopy and transmission electron microscopy revealed that the CBC fibers were intertwined and networks were loaded with well-distributed CoFe2O4 nanoparticles. With a CBC/CoFe2O4 ratio of 10 wt%, the optimal reflection loss (RL) of −45 dB at 8.6 GHz with a thickness of 2.0 mm because of the enhanced interfacial polarization related to the developed ɛ″. This novel electromagnetic nanocomposite material is believed to have potential applications in terms of microwave-absorbing performance.
