| 目的 以导电聚合物PEDOT:PSS作为电极和电致变色材料，通过棒涂、丝网印刷和凹版印刷等3种方式，实现导电聚合物纸基电致变色器件的制备。方法 通过溶剂(二甲基亚砜、异丙醇、甲醇、乙二醇、聚乙烯醇)掺杂的方式对3种印刷成膜特性进行优化;使用丙三醇提高PEDOT:PSS薄膜的导电性，采用PEDOT:PSS制作器件的变色层和电极层，简化变色器件结构。分别对变色器件的启动电压、变色效果、紫外吸收和弯曲等性能进行评价。结果 3种印刷方式均能实现纸基变色器件的制备，其中以凹版印刷方式制备的变色器件具有最佳的变色性能，即启动电压低(U=0.18 V)、响应时间短(t=2 s)、色差变化大(ΔE*=25.54)，变色前后吸光度变化大(0.27)，弯曲循环1000次后色差变化为1。结论 电致变色器件可以通过印刷的方式在纸基材料上进行制备，将纸基电致变色器件与印刷包装产品相结合，不仅能提高产品包装的外观表现，还可以增加产品包装的技术水平。 |

| Taking the conductive polymer PEDOT:PSS as electrode and electrochromic material, the paper-based electrochromic deviceswereprepared through three printing methods:rod coating, screen printing and gravure printing. We optimized the forming characteristics of the PEDOT:PSS film prepared by the three printing methods through doping with solvents (dimethyl sulfoxide, isopropanol, methanol and ethylene glycol, polyvinyl alcohol). In addition, glycerol was used to improve the conductivity of the film, and PEDOT:PSS was used as the color changing layer and the electrode layer of the device, which further simplifies the structure of the color changing device.The electrochromic devices wereevaluatedin terms of their starting voltage, color changing effect, ultraviolet absorption and bending performance. The results show that:All the above three printing methods can realize the preparation of paper-based electrochromic devices, and the device prepared by the gravure printing method has the best electrochromic performance, i.e., low starting voltage (U=0.18 V), short response time (t=2 s), great change in the color difference (ΔE=25.54), and large absorbance changes before and after the color change (0.27). The color difference changes to 1 after 1000 bending cycles. Therefore, electrochromic devices can be prepared on paper-based materials by printing. Combining paper-based color-changing devices with printed packaging products can not only improve the appearance of product packaging, but also increase the technical level of product packaging. |
