Thermally conductive MWCNTs/Fe3O4/Ti3C2Tx MXene multi-layer films for broadband electromagnetic interference shielding
文献摘要：
The Ti3C2Tx MXene is thought to be a promising candidate for next-generation electromagnetic interfer-ence(EMI)shielding materials.However,its broadband shielding capability and thermal conduction per-formance are insufficient to meet the growing demands.Herein,we reported a layer-by-layer composite film composed of Ti3C2Tx MXene,multi-walled carbon nanotubes(MWCNTs),and Fe304 nanoparticles.Benefitting from the architecture and the synergistic effect of components,the obtained composite film exhibited high comprehensive performance.Specifically,the introduction of Fe3O4 magnetic nanoparti-cles effectively reduced the impedance mismatch between the composite film and air and enhanced the magnetic loss of the composite film.The layered structure prolonged the transmission path of electro-magnetic waves inside the composite film and constructed a rich conductive network,causing interfacial polarization and ohmic loss.The results indicated that the composite film(52 μm)delivered a high EMI shielding effectiveness of 49 dB in the frequency range from X-band to Ku-band.Furthermore,the MWC-NTs layers in the composite films provided numerous heat transfer channels,reducing phonon scattering during heat transfer and resulting in a maximum thermal conductivity of 8.241 W/(m K).
