Abstract:

In order to develop a highly elastic and bistable electrochromic material for flexible electronic display devices, poly(2-hydroxyethyl acrylate)(PHEA) ionic gel based on hydrogen bond cross-linking network structure was prepared by solution polymerization. The hydrogen bond between the fluorane dye lactone ring and the polymer hydroxyl unit gave the fluorane dye color steadiness. The mechanical properties of PHEA ionic gel were tested by tensile testing machine. The transparency, electrochromic performance and bistable performance of the ionic gel device were characterized by potentiostat and spectrophotometer. The results show that PHEA ionic gel has tensile strength of 537 kPa and tensile resilience of 436%. The resulting electrochromic device is found to have responsiveness of 16.5 s, high coloration contrast of > 80%, bistability of 45 h, and reversibility of > 1 000 cycles, all of which are regarded as excellent. The ionic gel offers good application value in the development of stretchable electrochromic display and intelligent wearable electronic textiles.

Key words: bistability, electrochromic, ionic gel, smart textile, flexible material
