| 英文摘要 | Interest has been growing in electromagnetic interference (EMI) shielding materials in view of soaring EM radiation and its pollution control, which is necessary for public health and normal communication. To realize high EMI shielding effectiveness (SE), two factors of high electrical conductivity and strong multiple reflections are quite important. However, it is still a big challenge to obtain these two characteristics simultaneously in one material system. Here, we present a lightweight composite film integrating silver nanowires (AgNWs) as the skeleton and MXene as the covering decoration (AgNWs/Ti3C2Tx) for foaming structure. The composite film exhibits a low density of about 1 g cm(-3)and an electrical conductivity of up to 15 038 S cm(-1), which give a superiorly high specific EMI SE per unit thickness of 270 997 dB center dot cm(2)g(-1), and an EMI SE of 41.3 dB at a thickness of 1.2 mu m (or 96.7 dB at a thickness of 40 mu m) in the X-band. A film formation method of positive pressure filtration helps to easily control free space created during foaming for adequate EM wave scattering, yet remaining within the skin depth and strong multiple reflections have been achieved. The superior EMI shielding properties make the lightweight AgNWs/Ti(3)C(2)T(x)composite film a promising candidate in high-end applications. |
