Figure 3: Self-healing properties of the VSNPs-PAA electrolyte.
From: A self-healable and highly stretchable supercapacitor based on a dual crosslinked polyelectrolyte
(a) Demonstration of the self-healing process of VSNPs-PAA. (b) Demonstration of the self-healed VSNPs-PAA (3.4 mm thick and 1.8 cm wide) to completely support ca. 500 g mass, which equates to 80 kPa of stress: pristine sample (left of panel) and healed sample after the third breaking/healing cycle (right of panel). Red rectangles indicate the wound/healing positions. (c) Ionic conductivity of the VSNPs-PAA after multiple breaking/healing cycles. (Error bars are based on maximum and minimum values in five measurements.) (d) Schematic of self-healing arising from interfacial hydrogen bonding.
