Fig. 7: The rupture of LM-based NPs.
a The design of the polyurethane-based LM NP material150. b The morphology changes of different polyurethane-based LM NP materials150. c The stress-strain curves of different polyurethanes coupled with LM NPs activation stress, where the NPs break in the orange area and remain intact in the purple area150. d The experimental and theoretical activation strain of 50%LMNPs-0.3/85PU (50% vol% LMNPs-0.3 dispersed in 85PU matrix) and 50%LMNPs-1.4/85PU. The error bars show the standard deviation150. e The experimental and theoretical activation strain of 50%LMNPs-0.3/65PU and 50%LMNPs-1.4/65PU. The error bars show the standard deviation150. a–e Copyright 2021, Springer Nature.
