Fig. 1: Schematic illustration of the synthesis of epoxy supramolecular thermosets.

Schematic of vanillin-based epoxy resin, vanillin-based hyperbranched epoxy resin and vanillin derivatives bearing phenolic hydroxyl groups; and supramolecular networks prepared from hyperbranched topological structure. The epoxy supramolecular thermosets exhibits high toughness, high strength, closed-loop recycling, and rapid reprocessing simultaneously.
