a–d The strain dependence of the downshift in Raman G-band frequency rGO, MrGO, rGO-AD, and MrGO-AD sheets. e The proposed fracture mechanism of the MrGO-AD sheet, according to molecular dynamics simulations. Ti–O-C covalent bonding between MXene nanosheets and rGO platelets (elliptical region), π-π bridging interactions between AD molecules and rGO platelets (circular region), and sliding between MXene nanosheets (rectangle region). f–i Fracture morphology of the side views of MrGO (f, g) and MrGO-AD (h, i) sheets. Scale bar, 5 μm (f, h) and 1 μm (g, i).
