Super-stretchable and extreme temperature-tolerant supramolecular-polymer double-network eutectogels with ultrafast in situ adhesion and flexible electrochromic behaviour

We herein develop a new small molecule-based supramolecular-polymer double-network (SP-DN) eutectogel with high stretchability and toughness (>18 000% areal strain), and ultrafast (∼5 s) in situ underwater and low-temperature (−80 °C) adhesion.
