a Schematic illustration of our soft robotic systems, which can perform climbing and load-carrying. b The schematic diagram of fabricating the nanocomposites with vertically and horizontally aligned Al2O3@CNTs to the surface via applying an electric field. The top inset in (b) is the SEM image of the cross-section for the R-RT-TS sample. The inset at the bottom in (b) is the TEM image of the Al2O3@CNTs. The thickness of Al2O3 is about 5 nm. c, d The SEM images of the cross-section for the nanocomposites with vertically (c) and horizontally (d) aligned Al2O3@CNTs. e, f Raman shifts of the G-band at 1588 cm−1 of V-RT-TS (e) and H-RT-TS (f) membrane for the azimuthal angle of 0° and 90°, respectively. g, h XRD patterns (g) and the calculated crystallinity based on the XRD patterns (h) of the nanocomposites with different concentrations and orientations of Al2O3@CNTs.
