Abstract

Covalent organic framework (COF) materials are characterized by periodic π arrays and orderly open channels, but poor electrical conductivity limits their applications in opt-electric fields. In this paper, 2,4,6-tris(4-formylphenyl)-1,3,5-triazine (TFPT) and 2,4,6-tris(4-aminophenyl)-1,3,5-triazine (TAPT) were used to synthesize TPT-COF with a redox unit of triazine by Schiff base reaction. In order to improve the electrical conductivity of TPT-COF, we prepared Nickel Nanowires (NiNWs) by a chemical reduction method and then prepared TPT-COF/NiNWs composites with different loading amounts of NiNWs. With the addition of NiNWs, the two materials are assembled to obtain a nanorod structure by using the π–π packing effect of the COF and the bridging of function conductive NiNWs. The electrochemical properties of composite electrode materials with different contents of NiNWs were tested, and TPT-COF/NiNWs-15% exhibited better electrochemical performance in sulfuric acid electrolytes. The specific capacitance of TPT-COF/NiNWs-15% is 343 F/g, and the high power density is 10945 W/kg. The addition of NiNWs provides a good strategy to improve the electrical performance of the COF-based electrode materials.
