摘　　要：以具有三维层状结构的聚(苯噻唑并[5,4-d]噻唑)(p-PhTT)有机多孔聚合物作为前驱体,分别在600、700和800℃和氮气气氛下将其碳化得到一系列碳材料,进一步利用该碳材料制备工作电极并测试电容性能。与C-600和C-800电极相比,C-700电极拥有最好的电容性能,电流密度为0.5 A/g时有237.3 F/g的比电容。在功率密度为250 W/kg时,能量密度为9.9 W·h/kg;10000次循环后电容保持率为83.14%,有较好的循环稳定性。电极在电解质溶液中具有优异的离子扩散效率和电荷转移能力。Utilizing the organic porous polymer poly(phenylenethiazolo[5,4-d]thiazole)(p-PhTT)with a three-dimensional layered structure as a precursor,a series of carbon materials were obtained through carbonization under a nitrogen atmosphere at 600,700 and 800℃,respectively.The obtained carbon materials were used to prepare working electrodes and test their capacitive performance.The experimental results indicated that the C-700 electrode exhibited the best capacitive performance compared with the C-600 and C-800 electrodes,achieving a specific capacitance of 237.3 F/g at a current density of 0.5 A/g and an energy density of 9.9 W·h/kg at a power density of 250 W/kg.The capacitance retention rate reached 83.14%after 10000 cycles,and the electrode showed good cycling stability.The electrode exhibited excellent ion diffusion efficiency and charge transfer ability in electrolyte solutions.
