An ultralight and thermally conductive Ti3C2TxMXene–silver nanowire cellular composite film for high-performance electromagnetic interference shielding

MXene@Ag NW cellular composite films were successfully fabricated via a potassium ion induction and liquid nitrogen rapid pre-freezing strategy. The film delivers an ultrahigh EMI SE of 81.11 dB and a high thermal conductivity of 19.96 W m −1 K −1 .
