基于三维多孔石墨烯/含钛共轭聚合物复合多孔薄膜的柔性全固态超级电容器
Flexible All-Solid-State Supercapacitor Based on Three-Dimensional Porous Graphene/Titanium-Containing Copolymer Composite Film
摘要
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).关键词
