a Preparation schematic of PDA@OHG film. The cutout section of the PDA@OHG shows its core-shell structure. AAM: acrylamide, DA: dodecyl acrylate, PAM: polyacrylamide, PDA: polydodecyl acrylate, EG: ethylene glycol, red balls: oxygen, gray balls: hydrogen, yellow balls: carbon. b Scanning electron microscope (SEM) image of the PDA@OHG cross section. Scale bar: 50 μm. c Optical micrograph of the PDA-organohydrogel (OHG) interface of PDA@OHG. Scale bar: 20 μm. d Water contact angle (WCA) of the PDA and OHG. Scale bar: 500 μm. e Fourier transform infrared (FTIR) spectra of the as-prepared PDA and OHG. f Tensile stress-strain curves of the PDA, OHG, and PDA@OHG. g Photos of a PDA@OHG film in its initial and stretched state. Scale bar: 10 mm. Source data are provided as a Source Data file.
