Abstract

The invention provides a preparation method for a flexible electrode material for a super capacitor. The method is characterized in that a conductive gold coated fabric obtained by means of magnetron sputtering is used as a working electrode, and then a polypyrrole composite fabric is obtained from aqueous solution or acetonitrile solution containing p-toluenesulfonic acid and pyrrole monomers by means of electrochemical polymerization. The preparation method for the flexible electrode material for the super capacitor overcomes defects in the prior art, the prepared polypyrrole composite fabric not only has fabric features of breathability, flexibility and stretchability but also has conductivity of polypyrrole, and can still keep excellent electrochemical performances in the stretched state.

Description

technical field [0001] The invention relates to a preparation method of a flexible electrode material for a supercapacitor, belonging to the technical field of electrode materials. Background technique [0002] Wearable electronic products can be obtained by implanting electronic components in fabrics, so that clothing has more electronic information functions on the basis of maintaining comfort. Wearable electronics have promising applications in continuous personal health monitoring devices, high-performance sportswear, and flexible displays. However, all electronic products need power supply, so energy conversion or storage equipment with the unique properties of textiles such as light weight, flexibility, breathability and stretchability becomes necessary. [0003] As an emerging energy storage device, supercapacitors have the characteristics of high power density, short charging time, high cycle performance and energy saving, and have received extensive attention in th...
