Research of poly diamino-anthraquinone for supercapacitor electrode material

用电化学方法合成聚1,5-二氨基蒽醌导电聚合物材料,再添加一定比例的氯化铜得到新型聚合物,在4 mol/L的硫酸溶液中测试了聚合物的电容性能并研究了聚合物膜的导电性及形貌结构。结果表明:添加铜离子后,聚合电流响应变大,即促进了聚合物的合成,聚合物的排布和空间结构发生改变,还有一部分生成含铜络合物,材料表面孔隙率和比表面积增大,电导率提高,同时拥有大的比电容和循环性能。

Poly 1,5-diamino anthraquinone of conductive polymer materials was synthesized by electrochemical method and new polymer was acquired by adding some proportion of copper chloride to the solution. In 4 mol/L sulfuric acid solution, the capacitance performance of both kinds of polymers was tested and the conductivity and morphology structure of polymer membrane were researched. The results show that the polymerization current value of polymer with adding copper ion is larger. Copper ion promotes synthesis of the polymer so that polymer configuration and spatial structure change along with the formation of copper complex, which make material surface porosity, specific surface area and the conductivity increase, and the polymer has a large specific capacitance and good cycle performance.
