Weathering resistance of the function of an injection-moldable electrochromic multilayer film (BeSpECD)

拟议的研究项目的目的是表征具有特定层结构的柔性EC膜的耐候性，该层结构允许聚碳酸酯进行背面模塑。该项目是在前期项目中使用的聚合物电解质老化研究的基础上，针对具有特殊层结构的整体系统进行的。需要考虑的风化因素（影响因素）有：温度、湿度、紫外线照射、时间。要考虑的ECD属性（目标值）是：亮和暗状态下的透射率和颜色、透射率冲程、切换时间和循环稳定性。此外，将在无电解质和有电解质的情况下对单个组件（如半电池（工作电极和对电极））进行人工老化，以研究相互作用并更好地对ECD中发生的老化现象进行分类。预期的科学研究结果是对幼儿发展中的衰老原因、机制和现象的不同描述。此外，通过影响因素的系统变化（统计实验设计），影响变量和目标变量之间的函数关系将通过回归模型进行数学描述，并将允许识别相互作用效应，即一个影响因素对另一个影响因素的影响的依赖性。此外，注射压缩成型的新的可能性是用来封装的EC膜与聚碳酸酯的一部分，从而调查这种封装的耐久性（保护）的影响。将使用一个演示器，它可以与现有的模具插入生产。此外，将UV吸收剂引入以这种方式包覆成型的一些EC膜的胶囊中，以研究对EC膜对全局辐射的抗性的影响。这里的重点不是发现UV辐射会损坏ECD的有机组分或研究UV稳定剂的保护作用，而是研究由辐射引起的ECD温度升高的影响。

The aim of the proposed research project is to characterize the resistance to weathering of a flexible EC film with a specific layer structure that allows polycarbonate to be back-molded. The project builds on the aging investigations of the polymer electrolyte used in the previous project and is aimed at the overall system with the special layer structure. The weathering factors (influencing factors) to be considered are: Temperature, humidity, UV irradiation, time. The properties of the ECD to be considered (target values) are: Transmittance and color in the light and dark state, transmittance stroke, switching time and cycle stability. In addition, individual components such as half cells (working and counter electrodes) will be artificially weathered without and with electrolyte in order to investigate interactions and to better classify aging phenomena occurring in the ECD. The expected scientific findings are the differentiated description of the aging causes, mechanisms and phenomena in the ECD. Furthermore, by systematic variation of the influencing factors (statistical experimental design), the functional relationship between influencing and target variables will be described mathematically by means of a regression model and will allow the identification of interaction effects, i.e. the dependence of the effect of one influencing factor on another influencing factor. In addition, the new possibility of injection-compression molding is to be used to encapsulate part of the EC films with polycarbonate and thus to investigate the (protective) effect of this encapsulation on durability. A demonstrator will be used, which can be produced with existing mold inserts. Furthermore, UV absorbers are to be introduced into the capsule of some of the EC films overmolded in this way in order to investigate the effect on the resistance of the EC film to global radiation. The focus here is not on finding out that UV radiation can damage the organic components of the ECD or on investigating the protective effect of UV stabilizers, but on investigating the effect of the temperature increase of the ECD resulting from the irradiation.
