Spherulites of supramolecular polymers formed from undercooled melts, and their adhesive properties

The solid-state properties of crystalline supramolecular polymers have generally remained unexplored. Herein, we investigated the isothermal crystallization of a supramolecular polymer and showed that, depending on the temperature, it formed distinct structures at a higher hierarchical level. Interestingly, the resulting crystalline forms showed distinct adhesive properties and mechanical-failure modes (adhesive or cohesive).
