Abstract

Abstract: High-performance textile electrodes exhibit considerable potential for use as electronic devices in the wearable energy field. As silk fibroin protein can be dissolved, silk fabric is pretreated with a ternary solvent (CaCl2 /C2 H5 OH/H2 O) to increase the specific surface area of the substrate and the active material loading. The area capacitance of this fabricated electrode with ternary solvent treatment (PANI@TS-silk fabric, 4091.43 mF/cm 2 ) is 2.3 times that of an electrode prepared without ternary solvent treatment (PANI@WTS-silk fabric, 1811.43 mF/cm 2 ) and higher than the reported area capacitance of currently used flexible electrodes prepared using pure polyaniline. The capacitance retention rate of the PANI@TS -silk fabric electrode can reach 99.54% after 3000 charge-discharge cycles. The electrode can be used as a flexible sensor with stable performance under 2000 mechanical deformation. In addition, PANI@TS-silk fabric possesses good flame retardant performance, antimicrobial properties and UV resistance. These results suggest that the prepared PANI coated silk fabric has broad potential applications to wearable textiles. Graphical abstracts: Image, graphical abstract
