Interface-Confined High Crystalline Growth of Semiconducting Polymers at Graphene Fibers for Wearable Energy Devices. |
| 초록 |
Wearable energy storage devices have a great potential in numerous applications as they can operate in environments involving complex deformation modes. In this regard, graphene fiber-based supercapacitors have attracted much attention owing to the high conductivity and mechanical stability as well as very high surface area of graphene. As supercapacitors store energy through the phenomena of double-layer capacitance and pseudo-capacitance, increasing either or both of these increases the overall volumetric capacitance of these devices and consequently the energy density. In this work, we produced graphene-polymer core−shell fibers (G@PFs) in which nitrogen (N) and Copper (Cu) co-doped porous graphene fiber cores were uniformly coated with semiconducting polymer shell layers. Desirable combination of mechanical flexibility, electrochemical properties, and facile process scalability makes our G@PFs particularly promising for portable and wearable electronics |
