Covalent organic frameworks (COFs) possess extraordinary porosity, structural diversity, and good electrochemical performance, and have broad application prospects in the field of energy storage. However, the low conductivity of COFs limits its further development. In this paper, the electrochemical performance of triphenylamine-based COFs (TPA-COFs) was improved by compounding with highly conductive polyaniline (PANI) using solvothermal synthesis process. The highly conductive polyaniline fibers can act as conductive path in the composite to accelerate the charge transfer rate of TPA-COFs. The π-π interaction between TPA-COFs and PANI effectively decreases the agglomeration degree of PANI. The good dispersion of composite results in that the specific surface area of TPA-COFs/PANI-20 is high as 1233.9 m² g⁻¹, which provides rich diffusion channels for electrolyte ions. Moreover, the strong π-π structure in the composites ensures the stability of the material skeleton. Thus, TPA-COFs/PANI composite exhibits excellent rate characteristics and cycling stability.

用于超级电容器应用的高比表面积三苯胺基共价有机骨架/聚苯胺纳米复合材料

共价有机骨架（COFs）具有非凡的孔隙率、结构多样性和良好的电化学性能，在储能领域具有广阔的应用前景。然而，COFs的低电导率限制了它的进一步发展。本文通过溶剂热合成工艺与高导电聚苯胺 (PANI) 复合，提高了三苯胺基 COFs (TPA-COFs) 的电化学性能。高导电性聚苯胺纤维可以作为复合材料中的导电路径，以加速 TPA-COF 的电荷转移速率。TPA-COFs与PANI之间的π-π相互作用有效地降低了PANI的团聚度。复合材料分散性好，TPA-COFs/PANI-20的比表面积高达1233.9 m ² g^-1，为电解质离子提供丰富的扩散通道。此外，复合材料中的强π-π结构保证了材料骨架的稳定性。因此，TPA-COFs/PANI 复合材料表现出优异的倍率特性和循环稳定性。
