Healing Materials from V- and H-Shaped Supramolecular Architectures.

Chen, S., et al. Angewandte Chemie International Edition 2015, 54 (35), 10188-10192, DOI: http://dx.doi.org/10.1002/anie.201504136.

We report the rational design of novel V-shaped barbiturate (Ba) functionalized soft–hard–soft triblock copolymers with a reversible supramolecular healing motif (Ba) in the central part of the hard block, which undergoes autonomic repair at 30 °C. Self-assembling with heterocomplementary α,ω-Hamilton wedge (HW) functionalized polyisoprene (PI; HW-PI-HW), results in an H-shaped supramolecular architecture with efficient self-healing capabilities that can recover up to around 95 % of the original mechanical performance at 30 °C within 24 h.
