Carbon Dots Intercalated MXene for Flexible Organic Hydrogel Absorbers with Synergistically Enhanced Dielectric Loss

Caption

  • Catechol-functionalized carbon dots chemically anchor onto MXene nanosheets, enhancing interfacial polarization and enabling impedance matching optimization through glycerol-regulated gel polarity.
  • A flexible organic hydrogel absorber was constructed via synergistic integration of a dual-crosslinked polymer network and conductive MXene/carbon dots (CDs) hybrid fillers.
  • The MXene/CDs hydrogel exhibits outstanding performance (RLmin= −47.9 dB, 3.5 GHz bandwidth at 3.1 mm) together with improved mechanical robustness.
