Synthesis and Prototyping of Coloured Electrochromic Inks for Displays Applications

该项目的科学和技术目标是开发混合彩色EC油墨，以设计交互式显示器，并将其集成到实用的非阻塞性人机界面中。通过将这些材料集成到显示器中，旨在创建低功耗的交互界面，将人类与周围环境连接起来，可以简化我们的日常生活，为未来的城市带来巨大的财富。此外，对整个调色板的访问将为艺术家和设计师提供开发新的吸引人的方式的工具，以最愉快的方式构思这种人/环境界面。墨水将针对紫色、粉红色或橙子等颜色;而且，它们的理想特点是寿命长（超过10 K个周期），并缩短开关时间（对于150 x150 cm尺寸的原型，小于5秒）。墨水将由电致变色有机成分组成（聚噻吩聚合物或小杂原子掺杂的多环芳烃）和导电碳纳米结构（碳纳米管，碳纤维或石墨烯），并建立显示原型，其特征在于：（i）新的定制颜色与更环保的印刷溶剂相结合，（ii）减少响应时间并延长寿命

The scientific and technological aim of this project is to develop hybrid coloured EC-inks to engineer interactive displays to be integrated in practical, non-obstructive machine human interfaces. By the integration of these materials into displays, it is intended to create low-power interactive interfaces that, connecting human to the surroundings environment, could simplify our everyday life, bringing a great asset to the cities of tomorrow. Further, the access to a whole palette of colours will provide artists and designers the tools to develop new appealing ways to conceive such human/environment interfaces in the most pleasant ways. The inks will target colours such as purple, pink or orange; also, they will be ideally characterised by long lifetime (more than 10K cycles), and decreased switching time (less than 5 s for a prototype of 150x150 cm size).The inks will composed by an electrochromic organic component (polythiophenes polymer or small heteroatom-doped polycyclic aromatic hydrocarbons) and conductive carbon nanostructures (carbon nanotubes, carbon fibres or graphene), and to build display prototypes featuring: (i) new tailored colours combined to greener printing solvents and (ii) decreased response time and increased lifetime
