Facile synthesis of a hierarchical multi-layered CNT-NiFe2O4@MnO2 composite with enhanced microwave absorbing performance

The assembly of magnetic and dielectric materials around carbon nanotubes (CNTs) can create specific microstructures, leading to materials with relatively high microwave absorbing properties. Here, through a facile process, nickel iron oxide (NiFe2O4) is synthesized and placed on the surface of CNTs and this material is covered with manganese oxide (MnO2). In this hierarchical multi-layered nanomaterial (CNT-NiFe2O4@MnO2) produced though a …
