ABSTRACT
MXenes, a new class of two-dimensional (2D) materials and composites, have engrossed tremendous interest of researchers because of their promising characteristics, namely, high conductivity, tunable band gaps, flexibility, abundant surface terminal groups, and favorable mechanical properties. Their unique properties have enthralled researchers to find its extensive applications in several fields. The incorporation of self-healing ability in nanocomposites and other 2D materials augments the lifetime and usability of materials. Moreover, self-healing materials have opened a new era for an extensive range of applications. From 2010 to present, the quest for MXene-based composites have increased and become an engrossing area of research. Meanwhile, MXene/polymer nanocomposites have been developed and extensively studied for multifunctional applications. This chapter includes a meticulous discussion of the self-healing activity of MXene-based polymer nanocomposites, including their synthesis, healing mechanisms, and applications. The chapter also sheds new light on diverse methodologies involved in the synthesis of MXene-based composites having self-healing property, including their merits and demerits.
