Fig. 3: Self-healing and recyclability of PULM15 nanocomposite.
From: Photothermal modulated dielectric elastomer actuator for resilient soft robots
a Recovered toughness of PULM15 at different NIR light intensity for 30 min. b Recovered toughness of PULM15 at different healing times under NIR light of 0.2 W cm−2. c Optical microscope images of PULM15 damaged (left, 0 min) and healed after 120 min under NIR light of 0.2 W cm−2. d Digital images of PULM0 and PULM15 waste material before and after hot-pressing for 100 °C for 15 min. PULM0 failed to be recycled while PULM15 was successfully recycled into a film. e Tensile stress strain curve of PULM15 and recycled PULM15 (three cutting-recycling cycle) under a strain rate of 100 mm min−1. All error bars are the standard deviation of three independent samples.
