摘要

采用无水体系气液界面法,制备了高结晶度的Ni₃(HITP)₂,并测试了相关的电致变色性能。其光学对比度达到28.8%,着色响应时间为8.0s,较长的着色时间是由于较高的结晶度,导致离子难以嵌入。尽管如此,结晶度的提高使Ni₃(HITP)₂薄膜的原子排列更加有序致密,提高了结构的稳定性,导致更好的循环性能(100圈仍保持94%以上)。

Abstract

In this paper,Ni₃(HITP)₂ with high crystallinity was prepared by anhydrous system gas-liquid interface method,and the related electrochromic properties were tested.The optical contrast was 28.8% and the coloring response time was 8.0s.The longer coloring time was due to the high crystallinity,which made it difficult for ions to be embedded.Nevertheless,the increase of crystallinity made the atomic arrangement of Ni₃(HITP)₂ film be more organized and dense,improved the structural stability,and led to better cyclic performance (more than 94% after 100 cycles).
