通过将Ti 3 C 2 Tx纳米片和氧化石墨烯（GO）纳米片的悬浮液纺丝，然后在HI溶液中在80 °C下处理，制备具有上级柔性和高体积电容的Ti 3 C 2 Tx/还原氧化石墨烯（RGO-0. 9）纤维。在N2气氛中，5°C下，Ti 3C 2 Tx纳米片的氧化可以得到有效的保护，所制备的Ti 3C 2 Tx/RGO-0. 9纤维电极在1 M H2SO 4电解液中，电流密度为1 A cm− 3时的比容量为415 F cm− 3，并具有良好的上级柔性. Ti3C2Tx/RGO//PANI以Ti 3C 2 Tx/RGO-0.9纤维为负极，PANI/RGO-0.4纤维为正极，在PVA-H2SO 4凝胶电解液中组装成（聚苯胺）/RGO全固态非对称纤维超级电容器（AFSC），不仅在20 mA cm-3电流密度下表现出25 F cm-3的优异体积电容，而且在10.2 mW cm-3的功率密度下，能量密度高达3.4 mWh cm-3。组装后的AFSC具有良好的柔性和力学性能，弯曲500次后其体积电容无明显变化。高能量密度和上级机械柔性使其在便携式可穿戴电子设备等领域具有广阔的应用前景。
Ti3C2Txnanosheets/reduced graphene oxide (Ti3C2Tx/RGO-0.9) fiber with superior flexibility and high volumetric capacitance is prepared by spinning the suspension of Ti3C2Txnanosheets and graphene oxide (GO) nanosheets and followed by treating in HI solution at 80 °C. The oxidation of Ti3C2Txnanosheets can be effectively protected in N2atmosphereat 5°C, and the as-prepared Ti3C2Tx/RGO-0.9 fiber electrode shows a specific volume capacitance of 415 F cm−3at a current density of 1 A cm−3in 1 M H2SO4electrolyte and superior flexibility. Ti3C2Tx/RGO//PANI (polyaniline)/RGO all-solid-state asymmetrical fiber supercapacitor (AFSC) is assembled by using Ti3C2Tx/RGO-0.9 fiber as negative electrode and PANI/RGO-0.4 fiber as positive electrode in PVA-H2SO4gel electrolyte, it exhibits not only excellent volumetric capacitance of 25 F cm−3at a current density of 20 mA cm−3, but also high energy density of up to 3.4 mWh cm−3at a power density of 10.2 mW cm−3. Moreover, the assembled AFSC shows outstanding flexibility and mechanical property, its volumetric capacitance has no obvious change after bending 500 times. The high energy density and superior mechanical flexibility make it can be used as a promising flexible power source in the fields of portable wearable electronic devices.
