Abstract

Thermoplastic elastomer (TPE) is an applied engineering polymeric material having immense transformative potential for industrial applications because of its unique rubber like elasticity, thermoplastics like processability, good physico-mechanical properties, and excellent price-performance ratio. Until now, TPEs exhibiting self-healing properties have not been clearly understood due to their biphasic structure and thus remains a fascinating area in polymer science. This article aims to provide new ideas to develop next-generation self-healing TPE materials using innovative supramolecular polymeric networks via dynamic non-covalent interactions, like hydrogen bonding, ionic, coordination interactions, etc. which will facilitate the development of reversible association–dissociation characteristics of physical network structures in TPE. Recent advancements in self-healing TPE materials have been summarized. Extrinsic and intrinsic self-healing processes have been discussed with particular reference to TPEs. Finally, further prospective on self-healing TPEs have been critically discussed to inspire prospective research in this area. This review is expected to be useful for both the industries and academia for the development of new generation self-healing TPEs.
