a, b SEM and bright field TEM images (repeated independently with similar structures three times) of the cross-section and axial-section cut by focused ion beam and the corresponding model snapshots from theoretical simulations for MXene (a) and CSM (b) fibers. The first and fourth columns are SEM images, while the second and fifth columns are TEM images. The different MXene nanosheets in the model snapshots are post-rendered using different colors. Scale bars, 10 μm, 50 nm, 20 μm, and 10 nm from left to right. c Volume percent porosity of MXene fibers (blue) and the inner MXene layer in CSM fibers (red). d Herman’s orientation factor of wet (red) and dry (blue) MXene and CSM fibers. e Interplanar spacing of MXene (blue) and CSM (red) fibers. Data are presented as mean ± standard deviation from three independent experiments, where applicable. Source data are provided as a Source Data file.
