Electrospun Carbon/MXenes Nanofiber Composites for Electrochemical Capacitors

Abstract:

Herein, carbon nanofiber composites derived from polyacrylonitrile/MXene (PAN) using electrospinning technique are proposed as electrode for supercapacitors. Carbon/MXene composite nanofibers were successfully prepared at different MXene contents of 0, 4, 8, and 12 wt. %. Raman spectra displayed rising I_G/I_D ratio with increase MXene content. XRD results confirmed the embed MXene merged with carbon amorphous. The thermal stability of composite fibers was decreased with adding MXene. Carbon/MXene at 8 wt. % revealed the highest electrochemical supercapacitor of 155.25 F g^-1 at 1.0 A g^-1 with 100% capacitance retention after 10,000 cycles. Thus, PANMX8 has great potential for supercapacitor application with long-life cycles and fast-charging ability.
