Abstract:
In order to supply energy for wearable smart textile microelectronic functional components, flexible energy storage devices have become the important research. The electrode is an important component of the energy storage device and determines capacitance of the device. In this paper, a conductive silver-plated nylon fabric was used as the substrate, and zinc was loaded on the fabric surface by magnetron sputtering technology, then the conductive polymer polypyrrole (PPy) was constructed by both chemical and electrochemical polymerization. The morphology, electrical and electrochemical properties of the Zn@PPy fabric electrode was evaluated, and the influence of parameters such as chemical polymerization, electrochemical polymerization and magnetron sputtering time on the performance of fabric electrodes were investigated. The results show that Zn film can be uniformly grown on the fabric surface by magnetron sputtering with a surface sheet resistance of 1.51 Ω. Zn@PPy fabric electrode has a specific capacitance of 1185 mF/cm
2, which is 4.21 times higher than PPy/fabric electrode. This simple method of fabric electrode has potential applications in the field of microelectronic energy supply for wearable textiles.
