## Title

- title: Mechanochromism of dynamic disulfide bonds as a chromophoric indicator of
    adhesion strength for epoxy adhesive
  title_type: original
  lang: en

## Description

- description: We demonstrated that the introduction of disulfide bonds into epoxy
    adhesive could be used as a facile chromophoric indicator to predict the adhesive
    strength. Once the disulfide bond was cleaved, the color of the epoxy adhesive
    would be changed from yellow to green due to the generation of thiyl radicals.
    The lifetime of this green coloration, so-called mechanochromism, was dependent
    on the crosslink density of the epoxy adhesive, namely, the adhesive strength.
