【Abstract】 The 2D conductive material MXene（Ti₃C₂T_x）,electroactive tannic acid and robust aramid nanofibers are composited and vacuum-filtered to prepare self-supported flexible films with layer structure.The microstructure,morphology,mechanical and electrochemical performance of Ti₃C₂T_x/TA/ANF films are systematically investigated.The results show that Ti₃C₂T_x/TA/ANF film exhibits a high tensile strength of 36.2 MPa and excellent flexibility,which can be arbitrarily bent,folded and twisted.The Ti₃C₂T_x/TA/ANF film assembled flexible solid-state supercapacitor possesses a volumetric specific capacitance of 826.56 F cm^-3,a superior volumetric energy density of 28.7Wh L^-3and electrochemical stability under various bending angles.更多还原
