Improving the Properties of 2D Titanium Carbide Films by Thermal Treatment

Abstract

As a star of MXenes materials, 2D Titanium Carbide (Ti3C2Tx) has attracted broad interest of worldwide researchers in view of its potential application in energy storage, chemical sensing, electromagnetic interference shielding and flexible electronics. In order to further improve performances and satisfy the needs of the emerging flexible applications, there is an urgent need to increase the electronic conductivity, environmental stability and flexibility of Ti3C2Tx film. Herein, a two-stage thermal treatment process in argon atmosphere at low temperature (300 °C) is proposed to address this challenge. The resulting Ti3C2Tx film shows a 16-fold increase in electronic conductivity, while its environmental stability and flexibility are also greatly enhanced. Furthermore, systematical investigation on the microstructure and constitute variations of Ti3C2Tx films before and after thermal treatment shed light on the underlying mechanism, which contributes to a deeper understanding of MXenes’ property and offers a general guidance for improving the performance of MXenes film.
