Abstract: Herein, we report a de novo chemical design of supramolecular polymer materials (SPMs-1-3) by condensation polymerization, consisting of (i) soft polymeric chains (polytetramethylene glycol and tetraethylene glycol) and (ii) strong and reversible quadruple H-bonding cross-linkers (from 0 to 30 mol %). The former contributes to the formation of the soft domain of the SPMs, and the latter furnishes the SPMs with desirable mechanical properties, thereby producing soft, stretchable, yet tough elastomers. The resul… Show more

“…As a result, all of the samples exhibited similar stretchability at a strain rate of 20 mm min −1 (Figure S16). The higher strain rate would decrease the breaking elongation of the notch samples (Figure S17), which supported the proposed energy dissipation mechanism by noncovalent bonds because this noncovalent dissipation process usually exhibits dependence on deformation rates . All the samples with varied iron(III) ion contents exhibited considerable anti‐tearing ability (Figure S18).…”

“…Supramolecular provides even more rich molecular combination choices . One typical example is combining soft polytetramethylene glycol and tetraethylene glycol chains, as well as strong reversible quadruple hydrogen‐bonding cross‐linkers with molar ratio from 0% to 30% . The polymer could withstand a strain of up to 17 000% and show fracture energy of ≈30 000 J m −2 , which acts as a satisfactory stretchable substrate with high interfacial adhesion for gold electrodes.…”

“…Hydrogels represent an almost ideal candidate for mechanically compatible electrodes due to their inherent softness similar to tissue. The limitation here is the low conductivity of most hydrogels, especially for electrophysiological recording application . Using poly(3,4‐ethylenedioxythiophene) polystyrene sulfonate (PEDOT:PSS) modified with a highly conductive ionic liquid to improve the conductivity, conductive hydrogel electrodes with micropillar structure are achieved .…”
