Ice-Templated Large-Scale Preparation of Two-Dimensional Sheets of Conjugated Polymers: Thickness-Independent Flexible Supercapacitance |
| 초록 |
Two-dimensional (2D) organic materials hold great promise for use in a multitude of applications due to their outstanding properties. Herein, 2D sheets of poly(3,4-ethylenedioxythiophene):poly(4-styrenesulfonate) (PEDOT:PSS) are prepared from a commercially available PEDOT:PSS suspension using ice as a template. The 2D PEDOT:PSS sheets grow in the boundaries of ice crystals as the polymers are squeezed out of the suspension when the water solidifies. The mechanical robustness of the sheets can be enhanced by incorporating WO3 nanowires, and the PSS component can be conveniently removed with a concentrated solution of H2SO4 to afford stable suspensions of PEDOT or WO3@PEDOT sheets, either of which can be converted into flexible films with tunable thicknesses via filtration. Supercapacitors prepared from the WO3@PEDOT films exhibit outstanding energy-storage characteristics. The methodology described establishes an efficient and readily scalable approach for accessing 2D organic sheets. |
