采用Fe^（3＋）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r GO-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3μm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（0.76 N）。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）。

英文摘要：

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）-I-Ti was further prepared via electrochemical polymerization on the rGO-Fe substrate. As a new composite film, rGO-Fe/P（EDOT：P3C）-I-Ti film with average thickness of 3μm 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 （0.6A.g 1）.
