In this study, a CoFe2O4/C/PANI composite was developed through a green route, showing enhanced microwave absorbing performance and desirable wideband feature.
To solve the electromagnetic pollution, herein, a CoFe2O4/C/PANI composite was developed by a green route, which was constructed with spinel of metal oxide, graphitized carbon and conductive polymer composites. Benefiting from the designable interfaces and increased dipoles, the microwave dielectric response capability can be boosted significantly and resulted in the enhanced microwave absorbing performance. As revealed by the reflection loss curve, the minimum reflection loss (RLmin) reached - 51.81 dB at 12.4 GHz under a matched thickness of 2.57 mm. At 2.5 mm, the effective absorbing band covered 8.88 GHz, suggesting the desirable wideband feature. In our case, the method of utilization of a novel green way to fabricate multiple-component EM absorber can be a promising candidate for high-performance EM absorber.
