dc.description.abstractFabrication of smart materials for electromagnetic (EM) wave absorption has been propounded as effi- cient EM interference and pollution mitigation method. Herein, a porous lightweight graphe- ne@Ni 0.5 Co 0.5 Fe 2 O 4 composite was prepared via a coprecipitation method. The results show that Ni 0.5 Co 0.5 Fe 2 O 4 nanoparticles are homogeneously dispersed and anchored on the graphene flakes. Investigation of the EM waves absorption properties of the material at different filling in paraffin reveals that at 15 wt% loading, the composite absorbs large percent of the EM waves at minimal thickness. The composite attains optimum reflection loss peak 44.7 dB at 17.45 GHz, with 1.5 mm thickness. This enhanced EM wave absorption performance (at lesser thickness than Ni 0.5 Co 0.5 Fe 2 O 4 in literature) could be ascribed to interfacial polarization and a good impedance match arising from unique pore configu- ration of the dielectric (graphene) and magnetic (Ni 0.5 Co 0.5 Fe 2 O 4 ) composite. These results indicate that the lightweight G@Ni 0.5 Co 0.5 Fe 2 O 4 composites with strong absorption at reduced thickness is an efficient absorber for high-frequency EM wave attenuation.
