Titin-mimicking polycyclic polymers with shape regeneration and healing properties

Abstract

Polycyclic polymers based on cyclic (ABC)n-multiblock-copolymers are formed via stepwise polymerization of three individual blocks and exploiting the ring merging reaction of these ring polymers. The so-obtained precursor ring-polymers were interconnected via click reaction. Small blocks within the rings with the ability to form self-complementary hydrogen bonds lead to intra- and intermolecular links between polycyclic polymers. The obtained materials, which mimic nature's paragon Titin, have some extraordinary material properties concerning elasticity and energy dissipation.
