Integrated Carbon Nanotube and Ketoenamine‐Linked Covalent Organic Framework with Positive Charge Structure as High‐Performance Capacitive Materials
A series of composite materials, ETB@CNT (ETB@CNT10, ETB@CNT20, ETB@CNT30, ETB@CNT40, ETB@CNT50) with different carbon nanotubes (CNTs) contents are successfully prepared by using one-pot method. Compared with the pure ET-B-COF, which is a ketoenamine-linked covalent organic framework (COF) with a positive charge structure, CNTs can effectively improve the electrochemical performance of ET-B-COF, and the specific capacitance increased with the increase of the mass of carbon nanotubes added during the preparation process. Among them, ETB@CNT40 exhibits the best electrochemical performance (37.6 F g<sup>-1</sup>) at a current density of 1 A g<sup>-1</sup>. This study indicates that the simultaneous introduction of CNTs into COFs can significantly improve the electrochemical performance of ketoenamine-linked COFs materials.
