摘要：

Polymer-based layered conductive films used in electromagnetic interference (EMI) shielding and thermal management applications face a huge challenge of high contact electrical/thermal interfacial resistance. In this work, synergistic effect strategy between MXene and graphene nanoplates (GNP) is put forward to construct a directly contacted conductive network in polymer layered film. In detail, polyvinylidene fluoride (PVDF)-based layered films were prepared by the scalable blade-coating process. Under the above synergistic effect, a directly contacted in-plane electrical/thermal conduction network was obtained in the composite film. As a result, the MXene/GNP-PVDF composite film reveals both synergistic enhancements in electrical conductivity, EMI shielding effectiveness (SE) and in-plane thermal conductivity with the optimal values of 7423 S/m, 36.3 dB and 36.9 W/m K, respectively, which exceed those of the composite films with only MXene or GNP. Therefore, this work provides a simple synergistic strategy for the design and preparation of multifunctional EMI shielding and thermal management films.
