摘要
En 中文
• Bridge coupling of MXene and CCNTs created robust conductive networks in polyimide. • High EMI shielding of 32 dB was achieved at 42 μm with 3598 dB cm3 g−1 specific SE. • MXene and CCNTs provided synergistic flame retardancy to the PI composite film. • An excellent photothermal conversion of 81.3% PCE was reached under 1 sun irradiation. • Mechanical deformation triggers a pronounced and sensitive piezoresistive response.
