2D MXenes for flexible device applications

Abstract

Due to their distinguished electrical conductivity and mechanical flexibility, MXenes have emerged as fundamental nanomaterials in the development of various kinds of devices. These attributes position MXenes ahead of other 2D materials, such as graphene, in the fabrication of a wide array of flexible devices. Ease of synthesis and transparency add another feather to MXenes’ wings, enhancing their versatility. This review emphasizes the unique structural, mechanical characteristics, electrical, and surface characteristics of MXenes, tailored for the development of diverse flexible devices. The role of MXenes in a variety of flexible device applications, ranging from energy storage solutions such as supercapacitors, batteries, solar cells, flexible sensors, EMI shielding, electronic skins (e-skin), self-powered systems, transparent conductive electrodes (TCE), flexible displays, etc., has been explored. The review highlights the contribution of MXenes in improving the durability and efficiency of flexible electronics, thereby enhancing their operational lifespan. The use of MXenes in wearable and flexible devices has been explored to showcase their potential in advancing the design and manufacturing of these devices. MXene-based materials stand out not only for their exceptional performance but also for their role in driving forward novel applications, signifying a major shift in flexible electronics.The review provides essential insights into MXenes-based flexible device development, offering a framework for future advancements in the field of flexible devices.
