Fig. 1: Structural characterization and mechanical performance of SDM films.
From: Ultrastrong MXene films via the synergy of intercalating small flakes and interfacial bridging

a Photograph showing a lateral size of 13 × 10 cm2. b SEM image of a cross-section cut by a FIB. Scale bar, 2 μm. c Structural model illustrating the intercalation of small flakes and interfacial bridging by Ca2+ and borate ions. d 3D-reconstructed void microstructure by FIB/SEMT. Scale bar, 2 μm. e WAXS pattern for an incident Cu-Kα X-ray beam parallel to the film plane and corresponding azimuthal scan profile for the 002 peak. f Tensile strength and Young’s modulus of SDM films (red heart) are shown to exceed those reported for pure MXene films (green triangles) and MXene composite films (purple squares). The sample names, detailed data, and references corresponding to the sample numbers in this plot are in Supplementary Table 6.
