Characterization of the MXene-RSF interactions in solution. (A, B) TEM and SEM images of the pure RSF and MXene/RSF hybrid after assembly for 0 and 72 h. Red arrows indicate the morphology of the edge of MXene nanosheet. (C) Cryo-SEM images of the pure RSF and MXene/RSF hybrid after assembly for 72 h. (D) Raman spectra of MXene/RSF solution after incubation at 37 °C for different durations. (E) FT-IR spectra of MXene/RSF solution after incubation at 37 °C for different durations.
