【 摘 要 】

Self-healing polymers are the materials which can heal the internal cracks or damages automatically without any external intervention. The concept of self-healing has been derived from the biological systems such as human bone or skin which can heal automatically. This paper reviews the self-healing polymers based on Diels-Alder reaction where diene and dienophile groups form reversible covalent bond between them in the polymer matrix. A comprehensive review on Diels-Alder based self-healing composites reinforced with nano-fillers from the last decade have been reported here. The present status followed by future scope in this area has also been discussed briefly at the end of this review.
