Figure 6. (A) The stretch hysteresis of several acrylate adhesives. Incorporating with HEA or MA, the elastic energy is conserved rather than lost as heat[126]. Reproduced with permission. Copyright © 2019 Elsevier Ltd; (B) The pristine adhesive remained ~10% residual strain after 100 cycle hysteresis due to its newly formed hydrogen bonds. The pre-strained adhesive was recovered immediately[128]. Reproduced with permission.
