Fig. 2. Tough, self-healing polymers and ionic conductors.

a Design of the tough, self-healing elastomer and ionic conductor. b Stress–strain curves of the dog bone prepared with SHP-1 (black), SHP-2 (red), and SHP-3 (blue) with a sample width of 2 mm, a thickness of 2 mm, and a length of 10 mm at a loading rate of 100 mm/min. c Stress–strain curves of the dog bone prepared with SHP-1 (black) and SHIC-1 (red). d Graph comparing the toughness of materials. The data plotted represents the mean and standard deviation (n = 3, n means number of independent experiments). e Images of lifting 6 kg dumbbell using SHIC-1 film and SHIC-1 film with notch. f Stress–strain curves of SHIC-1 dog bone healed at room temperature. g A comparison of this work to recent work in self-healing ionic conductors.
