可穿戴电子设备需要在性能和灵活性方面不断改进。然而,很少有研究集中在高质量负载电极。在此,展示了一种3D打印方法,使用聚吡咯(PPy)纳米管作为电极材料在柔性碳布上制造高性能超级电容器。通过直接油墨印刷(DIW)技术,质量负载可以达到336.56 mg cm-2。此外,3D打印的超级电容器具有优异的机械稳定性,在120°的弯曲角度下,打印设备的电容保持93%。其良好的性能和优异的电化学稳定性将为可穿戴存储器件的制备提供一种理想的方法。
Wearable electronic devices need ceaseless improvement in performance and flexibility. However, few studies were focused on high mass loading electrodes. Herein, a 3D printing method was demonstrated to fabricate the high‐performance supercapacitor on flexible carbon cloth using polypyrrole (PPy) nanotubes as electrode materials. The mass loading could achieve 336.56 mg cm−2through direct ink printing (DIW) technology. In addition, the 3D printed supercapacitor exhibits excellent mechanical stability, the capacitance of the printed device remains 93% at the bending angle of 120°. Its promising performance and outstanding electrochemical stability will provide an ideal method to fabricate wearable storage devices.
