Figure 3. Self-adhesion and self-healing behaviors of the PCM organohydrogel. (A) Images demonstrating the tight adhesion of PCM organohydrogels to various materials; (B) Photographs exhibiting the excellent conformal adhesiveness of the PCM organohydrogel with no residue and no irritation on the human skin after 20 peeling cycles; (C) Schematic diagram of the lap shear measurements; (D) Adhesion strength of the PCM organohydrogel to different substrates; (E) Adhesion strength and reliability of the PCM organohydrogel to different substrates in four cycles; (F) Illustration of the self-healing feature of the PCM organohydrogel for a designed circuit; (G) Optical and (H) ultra-deep-field 3D images demonstrating the self-healing process of the PCM organohydrogel; (I) Tensile stress-strain curves and (J) the calculated HEs of the PCM organohydrogel with different healing time. PCM: PAM/CS/MXene; HEs: healing efficiencies.
