Self-healing materials

which can healing itself after damage

have achieved rapid development. Polymer materials with self-healing ability include extrinsic self-healing and intrinsic self-healing. There are growing concerns on intrinsic self-healing polymer materials since they have potential healing ability by itself and can achieve multiple repairing. Without or little external energy

intrinsic self-healing based on non-covalent interaction can be accomplished efficiently within few minutes. Those self-healing materials have a great significance for realizing energy conservation and sustainable development of society. Using different types of non-covalent bonds as clues

this review depicts the progress and application of intrinsic self-healing polymer materials. Furthermore

the developing direction of this field was also prospected in this review.
