摘要: 采用Fe³⁺离子交联的方法制备氧化石墨烯水凝胶，经化学还原制备出一种新型的三维多孔石墨烯薄膜材料命名为rGO-Fe；通过电化学聚合法在rGO-Fe基底上进一步制备了一种三维多孔石墨烯/含钛共轭聚合物复合薄膜材料，命名为rGO-Fe/P（EDOT：P3C）-1-Ti。作为一种新型复合薄膜材料，rGO-Fe/P（EDOT：P3C）-1-Ti较rGO-Fe具有更好的抗拉伸性能，平均厚度为3 μm的rGO-Fe/P（EDOT：P3C）-1-Ti薄膜，可承受载荷拉力0.97 N，优于相同厚度的rGO-Fe薄膜（0.76N）。将rGO-Fe/P（EDOT：P3C）-1-Ti薄膜作为自支撑电极制备了柔性全固态超级电容器，表现出优良的电容性能，且在弯折状态下仍能正常工作。当电流密度为0.1 A·g^-¹时，该柔性全固态超级电容器的质量比容量为71.13·F·g^-1，面积比容量为101 mF·cm^-2，当电流密度为0.6 A·g^-¹时，其质量比容量为18.14 F·g^-1，面积比容量为25.8 mF·cm^-2。

Abstract: A new three-dimensional (3D) porous graphene thin film named rGO-Fe was prepared through chemical reduction from Fe³⁺ ions cross-linking graphene oxide hydrogel, and a 3D porous graphene/titanium-containing conjugated polymer composite film named rGO-Fe/P(EDOT:P3C)-1-Ti was further prepared via electrochemical polymerization on the rGO-Fe substrate. As a new composite film, rGO-Fe/P(EDOT:P3C)-1-Ti film with average thickness of 3 μm can withstand the tensile load 0.97 N which is better than that of rGO-Fe (0.76 N). We compared the electrochemical properties of these film materials, and prepared self-supporting electrodes and a flexible all-solid-state supercapacitor based on rGO-Fe/P(EDOT:P3C)-1-Ti. Galvanostatic charge-discharge test results showed that the as prepared flexible supercapacitor delivered a gravimetric specific capacitance of 71.13 F·g^-1 (18.14 F·g^-1) and an area specific capacitance of 101 mF·cm^-2 (25.8 mF·cm^-²) at 0.1 A·g^-1 (0.6 A·g^-1).
