主　　题：Electromagnetic wave absorption CoFe_(2)O_(4)/C/PANI Interface polarization Effective absorption bandwidth 

摘      要：To solve the electromagnetic pollution,herein,a CoFe_(2)O_(4)/C/PANI composite was developed by a green route,which was constructed with spinel of metal oxide,graphitized carbon and conductive polymer *** from the designable interfaces and increased dipoles,the microwave dielectric response capability can be boosted significantly and resulted in the enhanced microwave absorbing *** 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 *** 2.5 mm,the effective absorbing band covered 8.88 GHz,suggesting the desirable wideband *** 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.
