Self-healing polymernanocomposite materials: A review

Highlights • Summarizes the current state of self-healing polymer nanocomposites. • Focuses on theoretical and experimental concepts. • Critical parameters affecting the self-healing properties of miscellaneous polymer nanocomposites. • Chemical structure–property relations in polymer nanocomposites.

Abstract During the last few years, different kinds of autonomic and non-autonomic self-healing materials have been prepared using diverse techniques for a number of applications. The incorporation of suitable functionalities into these materials facilitates a healing mechanism that is triggered by damage/rupture as well as various chemistries. This article presents a detailed study of the self-healing properties of different kinds of polymer nanocomposites utilizing a number of healing mechanisms, including the addition of several healing agents. The article will also provide an overview of different chemistries employed in the preparation of self-healing polymer nanocomposites , along with their advantages and disadvantages.
