Oxidation stability of Ti3C2Tx MXene nanosheets in solvents and composite films

Abstract Ti 3 C 2 T x belongs to the family of MXenes, 2D materials with an attractive combination of functional properties suitable for applications such as batteries, supercapacitors, and strain sensors. However, the fabrication of devices and functional coatings based on Ti 3 C 2 T x remains challenging as they are prone to chemical degradation by their oxidation to TiO 2 . In this paper, we examine the oxidation of Ti 3 C 2 T x in air, liquid, and solid media via conductivity measurements to assess the shelf life of Ti 3 C 2 T x MXenes. The oxidation of Ti 3 C 2 T x was observed in all the media used in this study, but it is fastest in liquid media and slowest in solid media (including polymer matrices).…
