Method for preparing PEDOT-based flexible electrochromic device through silk-screen printing method

The invention relates to a method for preparing a PEDOT-based flexible electrochromic device through a silk-screen printing method. The method comprises the following steps: performing silk-screen printing of PEDOT/PSS conductive ink on a pretreated transparent conductive substrate, performing thermal curing, sequentially printing conductive silver paste and an ultraviolet curing adhesive, and drying; and taking the obtained PEDOT electrochromic electrode as a working electrode, taking ITO-PET as a counter electrode, injecting TPU gel electrolyte, and performing packaging and hot pressing. Themethod is simple and convenient to operate, simple in required equipment, low in cost and suitable for preparation of large-area devices, and the prepared electrochromic device has good bending resistance and environmental stability. 本发明涉及一种丝网印刷法制备PEDOT基柔性电致变色器件的方法。该方法包括：将预处理的透明导电基底用丝网印刷PEDOT/PSS导电油墨，热固化，然后依次印刷导电银浆、紫外固化胶，烘干；以得到的PEDOT电致变色电极为工作电极，ITO-PET为对电极，注入TPU凝胶态电解质，封装热压。该方法操作简便，所需设备简单，成本低，适合大面积器件的制备，制备的电致变色器件具备良好的耐弯折特
