(A) Schematic illustrations of the fabrication process. (i) Macroscopic level: cellular monolith. (ii) Microscopic level: film-like cell wall. (iii) Nanoscopic level: AgNW network covered with the wrinkled RGO nanosheets and PAM chains. (B) SEM image of the compartmental wall of the AgNW/RGO aerogel. (C) Top-view SEM image of the ARAP hydrogel. (D, E) Magnified SEM images in (C). (f) Side-view SEM image and (G) EDS spectra of the hydrogel. Scale bars: 50 ​μm. Optical and SEM images of the knotted (H, J) and twisted (I, K) hydrogels. Reproduced with permission [85]. Copyright 2021, American Chemical Society.
