摘要

由于银粒子的快速成核和生长，电反射器件（erd）面临着诸如高电流密度和显著电压下降等挑战。通过醋酸盐与银离子的共价吸引，限制银离子的分布，使著色效率从46 cm2/C提高到93 cm2/C。erd的循环寿命超过1200次。此外，CH3COOLi的加入延长了器件的记忆效应18 min。这些发现为开发具有增强循环稳定性和记忆效应的高性能erd铺平了道路。

Color electro-reflective devices with long-term memory effect

Electro-reflective devices (ERDs) face challenges such as high current densities and significant voltage drops due to rapid nucleation and growth of silver particles. By limiting the distribution of silver ions through the covalent attraction of acetate and silver ions, the coloration efficiency was increased from 46 cm²/C to 93 cm²/C. ERDs have the cycle life of over 1200 cycles. Moreover, the addition of CH₃COOLi prolonged the memory effect of the device for 18 min. These findings pave the way for the development of high-performance ERDs with enhanced cycling stability and memory effect.
