Self-healing polymers from supramolecular architectures

Thursday, 5 November 2015

Integrating self-healing capability into supramolecular architectures is an interesting strategy, and can considerably enhance the performance and broaden the scope of applications for this important class of polymers.

German researchers from Martin-Luther-Universität Halle-Wittenberg (MLU) and Fraunhofer-Institut für Werkstoffmechanik report the rational design of novel V-shaped barbiturate (Ba) functionalised 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.

The designed synthesis also offers a suitable macromolecular building block to further self-assemble with heterocomplementary α,ω-Hamilton wedge (HW) functionalised polyisoprene (PI; HW-PI-HW), resulting 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.

The study is published in: Angewandte Chemie International Edition, Volume 54, Issue 35, August 24, 2015, Pages 10188-10192.
