Chapter 8 - Supramolecular network-based self-healing polymer materials

Abstract

Self-healing materials can recover their mechanical properties after fracture. The self-healing materials can save environment and resources by expanding lifetime of the materials. Starting with the first reports on self-healing materials in the early 2000s, the era of self-healing materials has started. Supramolecular chemistry is an attractive approach to realize the self-healing properties because of its reversibility. In 2008, the first report on supramolecular self-healing materials based on hydrogen bond was reported. Up to date, numerous methodologies for supramolecular self-healing materials have been reported. This chapter mainly focuses on the self-healing supramolecular materials based on host-guest chemistry and hydrogen bonds.
