Large-area Prussian blue film and preparation method thereof
The invention discloses a large-area Prussian blue film and a preparation method thereof, belongs to the technical field of electrochromism and ion batteries, and solves the problem that the large-scale production of the current large-area Prussian blue film is difficult to realize. According to the preparation method, trivalent iron ions are reduced by using MXene low-valence titanium elements to generate divalent iron ions, in-situ growth of the Prussian blue film is realized on the basis of coordination of the divalent iron ions and ferricyanide in a solution, and the Prussian blue film with a proper thickness is obtained by adjusting the concentration of MXene, the coating frequency and the reaction time. The preparation process of the large-area Prussian blue film provided by the invention does not need high-temperature treatment, strict preparation conditions and complex preparation equipment, the process is simple and rapid, the size of the conductive substrate is not limited, and large-scale preparation of the Prussian blue film is easy to realize; and an efficient way is provided for practical application of the Prussian blue film in electrochromic devices and ion batteries.
本发明公开了一种大面积普鲁士蓝薄膜及其制备方法，属于电致变色及离子电池技术领域，解决当前大面积普鲁士蓝薄膜大规模生产难以实现的问题。该制备方法利用MXene低价钛元素还原三价铁离子生成二价铁离子，基于二价铁离子与溶液中的铁氰根配位实现普鲁士蓝薄膜的原位生长，通过调节MXene浓度、涂布次数及反应时间获得合适厚度的普鲁士蓝薄膜。本发明提供的大面积普鲁士蓝薄膜制备过程无需高温处理、严苛制备条件和复杂的制备设备，工艺简单快捷且导电基底尺寸不受限制，易于实现普鲁士蓝薄膜的大规模制备，为普鲁士蓝薄膜在电致变色器件及离子电池中的实际应用提供一种高效的途径。
