Concepts and properties of the materials (IMAGE)
Caption
Concepts and properties of the materials. a) Conceptual illustration of the various applications of the material. b) Schematic of the fabrication process and the underlying chemistry. c) Fourier transform infrared (FTIR) spectra of synthesized materials. d) DSC profiles assessing the intrinsic polymeric structure of the materials (n = 3). e) Photographs of the as-prepared samples. f) Quantification of water content in the samples as a function of filler concentration (n = 8). g) Efficient reassembly of the components after being torn apart. SEM images presenting a detailed examination of the rapid self-healing property inherent in P40 (n = 3). h) A cyclic demonstration of the spontaneous healing of the electronic circuit. The approximate recovery time for each cycle is 20 s (n = 4). i) Relationship between added fillers and conductivity (n = 5). j) Quantified adhesion strength on steel, brass, PET, polydimethylsiloxane (PDMS), skin, muscle, heart, and tendon, further emphasizing the versatility of P40 as an adhesive. k) Ability of P40 to heal broken muscle tissue both mechanically and electrically (n = 4). All data are presented as mean ± SD. Illustration: Daniel Müller.
