Bio-inspired surface functionalization of highly porous carbon nanosheets for enhanced supercapacitor performance |
| 초록 |
Redox-active organic materials have attracted considerable interest as promising pseudocapacitive materials for energy storage applications because they have large gravimetric energy density, low cost and mechanical flexibility. Furthermore, the low conductivity and poor cyclability of organic molecules can be readily improved by integrating them with conductive porous carbon materials, leading to pseudocapacitive electrodes with high energy and power densities. Herein, we report a novel bio-inspired surface functionalization of highly porous carbon nanosheets using the formation of a polydopamine coating and the subsequent layer-by-layer deposition of ferric ions (Fe3+) and tannic acid. The polydopamine coating provided functional groups for redox reactions and metal coordination, while the Fe3+/tannic acid layers improved the cycle stability, given the strong catechol-Fe3+ interactions. |
