摘要

The ternary composites of reduced graphene oxide-polypyrrole-NiFe ₂O₄ (RGO-PPy-NiFe₂O₄) were synthesized via a two-step method and the electromagnetic absorption properties were investigated. The average diameter of NiFe₂O₄ particles on RGO-PPy ranged from 10 to 20 nm. The results revealed that the electromagnetic absorption properties and the absorption bandwidth of RGO-PPy-NiFe₂O₄ are much better than RGO-PPy. The maximum reflection loss of RGO-PPy-NiFe₂O₄ is -44.7 dB at 14.9 GHz and the absorption bandwidth with the reflection loss below -10 dB is 4.7 GHz with a thickness of 1.75 mm. Furthermore, our strategy provides a feasible method to obtain the ternary composites with excellent electromagnetic absorption properties and wide absorption bandwidth for future investigators.
