MXene based flexible materials for energy harvesting

Flexible energy-harvesting materials can adapt to irregular topography and achieve self-supply of power, which has great potential for applications in wearable, surface interface engineering, digital healthcare, etc. MXene, as an emerging two-dimensional material, can be combined with various flexible materials and provide optimized action in energy harvesting. Moreover, the unique structural features of MXene also determine its special physicochemical properties, making it easy to endow MXene-based materials with multifunctional properties. This paper starts with the applications of MXene in different energy capture, including solar energy, thermal energy, mechanical energy and so on. The structure and fabrication process of MXene are also summarized. Afterwards, the realization scheme of MXene-based flexible materials are described in detail. Finally, perspectives of MXene based flexible energy harvesting, especially for wearable self-powered devices, are proposed.
