Built‐In Interfacial Electric Field in Hydroxyl‐Terminated MXene/COF Heterostructures for Enhanced Solid‐State Supercapacitors

open access: yesAdvanced Functional Materials, EarlyView.
Hydroxyl‐terminated MXene is integrated with a redox‐active covalent organic framework through electrostatic self‐assembly followed by hydrothermal treatment to construct MXene/COF heterostructures with a built‐in interfacial electric field. Termination‐controlled interfacial electronic modulation induces charge redistribution and favorable band ...
