Elastomers are highly valued soft materials finding many applications in the engineering and biomedical fields for their ability to stretch reversibly to large deformations. Yet their maximum extensibility is limited by the occurrence of fracture, wh

A mechanochemistry based approach is proposed to detect and map stress history during dynamic processes. Spiropyran (SP), a force sensitive molecular probe, was incorporated as a crosslinker into multiple network elastomers (MNE). When these mechanoc

Significance Soft materials can be toughened by creating dissipative mechanisms in stretchy matrixes. Yet using them over a wide range of temperatures requires dissipative mechanisms independent of stretch rate or temperature. We show that sacrificia

Description
Tough elastomers that resist fracture at high loads are not optimum for sustaining many cycles at low loads.
Although elastomers often experience 10 to 100 million cycles before failure, there is now a limited understanding of t

Embedded spiropyran mechanophores reveal and quantitatively map stresses in soft materials by changing their color.
Directly quantifying a spatially varying stress in soft materials is currently a great challenge. We propose a method to do that

The use of the rheometric quartz crystal microbalance (QCM) as a quantitative cure monitor for photocuring systems was demonstrated. The technique requires the use of films with thicknesses in the micrometer range and is based on the direct measureme
