摘要

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 (RL_min= −47.9 dB, 3.5 GHz bandwidth at 3.1 mm) together with improved mechanical robustness.
