Structurally integrated Ti3C2Tx MXene/cotton fabric electrodes for supercapacitor applications

Abstract

This study investigates the electrochemical performance of Ti3C2Tx 3 C 2 T x MXene-coated cotton fabric electrodes for supercapacitor applications. The sediment and supernatant parts of synthesized Ti3C2Tx 3 C 2 T x MXene were applied onto cotton substrates through a drop-casting technique at various concentrations to explore the influence of MXene dispersion density on the structural, morphological, and electrochemical properties of the fabric electrodes. Findings indicate that the lower-concentration dispersions not only improve the structural integrity of the coatings but also enhance their electrochemical functionality. The fabric electrodes fabricated from MXene supernatant exhibited significantly lower electrical resistance (7.3 Omega sq-1)- 1 ) and higher specific capacitance, reaching 488 F g- 1 at a current density of 0.5 A g- 1 . The study demonstrates the potential of MXene-coated fabrics as adaptable and efficient energy solutions for wearable technologies, highlighting that tuning the concentration and post-synthesis parameters of MXene dispersions can effectively alter their electrochemical properties.
