Fig. 5From: Advances in self-healing supramolecular soft materials and nanocomposites(reproduced with permission from: Ref. [52], ©2018 ACS)a Chemical structures of supramolecular polymeric materials (SPMs) with different amounts of stronger UPy quadruple H-bonding and weaker urethane cross-links to tune the properties of SPMs; b schematic illustration of the construction of highly stretchable SPMs; c GPC chromatograms utilizing DMF as the eluent and PMMA as the standard, showing that all polymer are comparable Mn and relatively narrow PDI, respectively; d SAXS profile of bulk SPMs that displays broad scattering peaks at 3.7 to 5.2 nm, indicative the presence of microphase separation; e optical images of the damaged and healed SPM filmBack to article page
