Abstract Binder-free Ti3C2 MXene/carbon nanotubes (Ti3C2/CNTs) films were successfully deposited onto graphite paper via electrophoretic deposition (EPD) method for supercapacitor electrodes. The as-prepared Ti3C2/CNTs electrode exhibits enhanced specific capacitance, approximately 1.5 times and 2.6 times of that of pristine Ti3C2 and CNTs films, respectively. Impressively, Ti3C2/CNTs electrodes demonstrate excellent cycling stability, without capacitance decay over 10,000 cycles. Incorporation of CNTs into MXene builds a robust structure, preventing MXene from restacking, and thus leading to the enhanced electrochemical performance. These results suggest that robust Ti3C2/CNTs films can be prepared by a simple yet effective EPD method, potentially applicable to other hybrid MXene systems.

通过电泳沉积制备用于超级电容器电极的 MXene/CNTs 薄膜

摘要 无粘合剂 Ti3C2 MXene/碳纳米管 (Ti3C2/CNTs) 薄膜通过电泳沉积 (EPD) 方法成功沉积在石墨纸上用于超级电容器电极。所制备的 Ti3C2/CNTs 电极表现出增强的比电容，分别约为原始 Ti3C2 和 CNTs 薄膜的 1.5 倍和 2.6 倍。令人印象深刻的是，Ti3C2/CNTs 电极表现出优异的循环稳定性，在 10,000 次循环中没有电容衰减。将碳纳米管并入 MXene 可构建坚固的结构，防止 MXene 重新堆叠，从而提高电化学性能。这些结果表明，坚固的 Ti3C2/CNTs 薄膜可以通过简单而有效的 EPD 方法制备，可能适用于其他混合 MXene 系统。
