Fully self-healable, highly stretchable, and anti-freezing supramolecular gels for energy-harvesting triboelectric nanogenerator and self-powered wearable electronics

Metal-free triboelectric nanogenerators for application in wearable electronics

“…11 Conventional supports with self-healable behaviors are introduced with organohydrogels crosslinked with phytic acid and coated with PEDOT:PSS as an active conductive layer. 90 An alternative to the substitution of conducting polymers is explored through the use of ionic hydrogels applied mutually as an electrification layer and electrode. 91 For applications in which transparency and stretchable-freezing tolerant devices are required, conductive gelatin/NaCl organohydrogels 92 introduce long-term stability in association with freezing resistance and self-healing properties.…”

Highly stretchable, tough, healable and mechanoresponsive polyurethane elastomers for flexible capacitor applications

“…On the other hand, there should be reversible bonds present in intrinsically healing materials that can recover by themselves after damage. Extrinsic healing processes are widely explored in thermosets and primarily epoxy resins, 8–10 whereas intrinsic healing processes are intensively studied in elastomers, such as silicones, 11 polyurethanes, 12 and general purpose rubbers. 13–15 Lately, non-covalent interactions ( e.g.…”

Ionic Thermoelectric Effect Inducing Cation‐Enriched Surface of Hydrogel to Enhance Output Performance of Triboelectric Nanogenerator

“…[23][24][25] Hence, it becomes important to control the interface charge density by changing the properties of friction materials. [16,26,27] The most robust consensus related to ionic-hydrogel-based triboelectric nanogenerator (TENG) is that the charge density at the solid interface plays a pivotal role in its output performance. However, there has been no reliable evidence of the mechanism regarding the influence of ion enrichment on TENG.…”
