Fig. 3: Microscopic characterization of the MXene/liquid metal composite prepared by solvent-assisted dispersion (MLM-S).

a Photograph of an MLM-S coated weighing paper. b SEM image of the MLM-S coating surface. b1–4 EDS mapping of the region b. c SEM image enlarged from the orange box region in b. c1–4 EDS mapping of the region c. d Schematic diagram illustrating the blade coating of the MLM-S plasticine. The image is generated using 3D modeling software. e 3D reconstruction image of the MLM-S plasticine generated by collecting and reconstruction 2D projection images by X-ray microscopy (XRM). The blue part represents MXene, while the orange portion represents LM. The LM is made semi-transparent to more clearly show the MXene inside. f Slice image of e exhibiting the horizontal section. g Backscattered electron image of MLM-S coating surface. h AFM phase image and i AFM 3D height image of the M2LM-S coating. j SEM image of the MLM-S coating under 90° bending. The area between the two white dashed lines is where the MLM-S coating bends.
