Low-Cost Fabrication of High-Performance Fluorinated Polythiophene-Based Vis–NIR Electrochromic Devices toward Deformable Display and Camouflage

Chemistry of Materials, Journal Year: 2022, Volume and Issue: 34(22), P. 9923 - 9933

Published: Nov. 2, 2022

Flexible electrochromic devices (FECDs) are extensively used in smart windows, deformable electronic displays, and wearable electronics. However, it remains very challenging to fabricate low-cost yet high-performance visible–near-infrared (vis–NIR) FECDs. In this work, we overcome hurdle by developing a fluorinated polythiophene derivative with superior overall performance simple electropolymerization patterning. Fluorophenyl-modified (band gap: 1.74 eV) can be readily synthesized via one-step Grignard coupling high yield of >90% together successive low-potential at 1.0 V vs Ag/AgCl. The intermolecular hydrogen bonding from the fluorine substitution backbones allows facile electrodeposition free-standing polymer films compact morphology also leads mechanical strength electrical conductivity enhancement. Interestingly, such exhibit intriguing performances reversible color changes between deep red light green upon doping/dedoping, including optical contrast throughout NIR region (max. 80% 1600 nm), fast response time (0.93 s), coloration efficiency (up 752 cm2 C–1), outstanding stability against cycling (<3% reduction after 5,000 cycles), excellent memory effect. fabricated FECDs patterning polymers display robust (<5% decay bending cycles radius 1 cm) under low driving voltage (0.85 V). We further demonstrate applications patterned toward color-changing on-skin tattoos, infrared camouflage stable color-switching properties.
