The cracking of electrochromic materials due to aging or reiterative bending is a major problem which noticeably degrades the performance of electrochromic devices. In the present research, we successfully induced a triphenylamine derivative into furfuryl glycidyl ether, and further by a DA cross-linking polymerization reaction with maleimide (MA) to yield polymer DATPFMA. The color of the polymer film could be switched from faint yellow to green grey to dark blue. The observed coloration efficiency values of the polymer for the electrochromic process were 82.2 and 175.3 cm² C⁻¹ at 580 and 1060 nm, and the coloring and bleaching response times were 4.1 and 11.0 s, respectively. The self-healing process of the polymer film at 110 °C was observed by optical microscopy and the self-healing rate was about 80%. The results indicate that the polymer DATPFMA is a novel electrochromic material with noteworthy self-healing properties.

基于三苯胺交联聚合物的新型自修复电致变色膜

由于老化或反复弯曲导致的电致变色材料的破裂是一个主要问题，其显着降低了电致变色器件的性能。在本研究中，我们成功地将三苯胺衍生物诱导成糠基缩水甘油醚，并进一步通过与马来酰亚胺（MA）的DA交联聚合反应生成了聚合物DATPFMA。聚合物膜的颜色可以从微弱的黄色变为绿灰色，再变为深蓝色。观察到的电致变色聚合物的着色效率值为82.2和175.3 cm ² C ^-1在580nm和1060nm处，着色和漂白响应时间分别为4.1和11.0s。通过光学显微镜观察到聚合物膜在110℃下的自修复过程，并且自修复率约为80％。结果表明，聚合物DATPFMA是一种新型的电致变色材料，具有值得注意的自修复性能。
