capacitance carbon nanotubes sandwich-like structures flexible films MXene ESI Highly Cited Paper (Incites)
Free‐standing and flexible sandwich‐like MXene/carbon nanotube (CNT) paper, composed of alternating MXene and CNT layers, is fabricated using a simple filtration method. These sandwich‐like papers exhibit high volumetric capacitances, good rate performances, and excellent cycling stability when employed as electrodes in supercapacitors.
