Abstract

The invention discloses a preparation method of a high-performance flexible silk fabric electrode material and a product thereof. The preparation method sequentially comprises the following steps: (1)adding a silk fabric into a solvent containing a ternary solution (CaCl2 / H2O / C2H5OH with the molar ratio of 1: 8: 2), temporarily and slightly dissolving the fabric for a period of time under the conditions of heating and water bath oscillation, washing with water and drying; (2) adding the fabric obtained in the step (1) into a sulfuric acid and aniline monomer mixed solution, and stirring for aperiod of time; (3) adding a mixed solution of sulfuric acid and ammonium persulfate into the step (2), and stirring to react for a period of time; and (4) washing and drying the reacted fabric to obtain the flexible fabric electrode material. The raw material cost is low, the preparation method is rapid, simple, convenient and effective, industrial production is easy, and the prepared fabric electrode has both flexibility and high area specific capacitance and has very good potential application value in the fields of flexible supercapacitors and wearable devices.

Description

technical field [0001] The invention belongs to the field of preparation of flexible fabric electrode materials, in particular to a preparation method of high-performance flexible silk fabric electrode materials and products thereof. Background technique [0002] With the development of mobile communication and information technology, especially portable consumer electronic devices and biomedical micro-devices, there is an increasing demand for wearable devices. Conventional supercapacitors are not mechanically strong enough to withstand bending cycles for extended periods of time. Therefore, it is highly necessary to explore flexible electrodes with both high capacitance and high mechanical strength. Compared with conventional film-type flexible supercapacitors, the use of textile materials can significantly release the mechanical stress induced in the bending, twisting, and stretching deformations that often occur under wearing conditions, resulting in excellent flexible ...
