摘　　要：多孔芳香框架由于其含氮量高,优异的化学稳定性等优点广泛应用于超级电容器、气体的吸附与分离等方面。在论文中,笔者使用以三聚氯氰和2,5-二氨基吡啶二盐酸盐为构筑单元,合成了三嗪基多孔聚合物TPOP,并制备了不同结构的氮掺杂炭材料,探究了三电极和对称电极超级电容器方面的应用。三电极超级电容器测试表明,炭化温度为700℃得到的炭产物构建的三电极超级电容器在0.5 A/g时比电容达到195 F/g,远高于聚合物前驱体的电容量。对称超级电容器测试表明,相应炭产物的比电容为46.9 F/g,能量密度为16.7 Wh/g,表明该材料在超级电容器中具有良好的应用潜力。Porous aromatic frames are widely used in supercapacitors,gas adsorption and separation due to their high nitrogen content and excellent chemical stability.In this paper,the authors use melamine and 2,5-diaminopyridine dihydrochloride as building units to synthesize the triazine-based porous polymer TPOP,and prepared nitrogen-doped carbon materials with different structures,explored the application of three-electrode and symmetrical electrode supercapacitors.The three-electrode supercapacitor test showed that the three-electrode supercapacitor constructed from the carbon product obtained at a carbonization temperature of 700°C reached a specific capacitance of 195 F/g at 0.5 A/g,which is much higher than the capacitance of the polymer precursor.Symmetric supercapacitor tests show that the specific capacitance of the corresponding carbon product is 46.9 F/g and the energy density is 16.7 Wh/g,indicating that the material has good application potential in supercapacitors.
