摘　　要：利用氯磺酸共混碳纳米管与过渡金属碳化物MXene形成液晶态纺丝液,通过湿法纺丝技术制备CNT/MXene复合纤维,分别使用电化学沉积法及水热法在复合纤维表面沉积二氧化锰(MnO_(2)),制备MnO_(2)@CNT/MXene复合纤维,纤维用固态电解质封装成为柔性超级电容器。结果表明,电化学沉积较水热法沉积的纤维超级电容器具有更高的体积比电容,在1 A/cm^(3)的电流密度下的比电容约为97.5 F/cm^(3),在循环充放电2500次后,最终电容保持率约为原有的74.5%。The combination of one-dimensional carbon nanotubes and two-dimensional transition metal carbon/nitride(MXene),using the electrochemical deposition method and the hydrothermal method to deposit manganese dioxide(MnO_(2))on the surface of the composite fiber.The results indicated that the fiber supercapacitor deposited by electrochemical deposition has a higher volumetric specific capacitance than the fiber supercapacitor deposited by hydrothermal method.The specific capacitance at a current density of 1 A/cm^(3)is about 97.5 F/cm^(3).After 2500 cycles of charging and discharging,its final capacitance retention rate is about 74.5%of the original.
