中文摘要: |
目的 由于PET-ITO电极的刚性脆性限制了柔性ECD的性能及其发展,使用高导电率的纳米银线(AgNWs)电极对其进行改进。方法 采用乳液聚合法制备PANI墨水,借助PVA薄膜的双功能性(黏附性和绝缘性),基于丝网印刷、喷涂印刷、涂布印刷3种工艺制备无ITO基的全印刷型 PET-PVA-AgNWs-PANI ECD。结果 通过印刷制备复合PVA的PET-PVA-AgNWs-PANI电极具有良好的电学性能和稳定性(方阻稳定维持在10 Ω/sq以下),以此电极为基础的ECD具有48.04%的最大光调制能力和一定的红外光调制能力。结论 以印刷为基础制备的无ITO基多色电致变色器件具有良好的柔性和变色性能,可广泛应用于智能包装和智能窗户等场景。 |
英文摘要: |
Since the rigidity and brittleness of PET-ITO electrodes limits the performance and development of flexible ECDs, the work aims to improve them with high conductivity silver nanowires (AgNWs). Therefore, the PANI ink was prepared by emulsion polymerization, and the ITO-free fully printed PET-PVA-AgNWs-PANI ECDs were prepared based on three processes, namely screen printing, spray printing, and coating printing, with the help of the bifunctionality of the PVA film (adhesive and insulating properties). The PET-PVA-AgNWs-PANI electrode with composite PVA prepared by printing had good electrical performance and stability (square resistance stably maintained below 10 Ω/sq). The ECDs based on PET-PVA-AgNWs-PANI also featured 48.04% visible light modulation and certain infrared light modulation. The ITO-free multicolor electrochromic devices prepared on the basis of printing have good flexibility and color change performance, which can be used widely in the scenarios of smart packaging and smart windows. |
