Electrochemical Properties of O-diketone Conjugated Porous Polymers in Capacitors

本文以均苯三甲醛、双乙酰作为反应物,吡咯烷作为催化剂,通过羟醛缩合反应在甲醇溶剂中得到邻二酮共轭多孔聚合物。该材料孔径分布范围为2~38 nm,说明其具有介孔结构。由于邻二酮共轭多孔聚合物良好的CV曲线,进一步进行超级电容器与电池性能测试,发现其在酸性条件下超级电容器的比电容可到达20 m F·cm-2。

In this study,benzenetrimethanol and diacetyl were employed as reactants,with pyrrolidine as the catalyst,to synthesize conjugated porous polyimides via hydroxyl aldehyde condensation in methanol solvent.The material exhibited a pore size distribution ranging from 2 to 38 nm,indicating its mesoporous structure.Due to the favorable cyclic voltammetry(CV)curves of the conjugated porous polyimides,further performance testing was conducted for supercapacitors and batteries.It was found that the specific capacitance of the supercapacitor could reach up to 20 mF/cm-2 under acidic conditions.
