Highly conductive Ultraflexible Graphene

石墨烯的独特性质使其成为各种应用的理想选择，特别是超柔性电子设备，如显示器、触摸屏、电子纸、智能包装和智能纺织品。这些需要柔性导电薄膜作为电极和互连，而金属薄膜或栅格目前被用作显示器和触摸屏的背板。然而，除了价格昂贵外，这些材料还具有环境不稳定、易碎和不完全灵活(例如，可整合)的特点。石墨烯作为一种柔性导电层，可以巩固塑料电子的低温加工、印刷灵活性和较低的制造成本等优势。该项目旨在展示石墨烯作为柔性有源矩阵阵列中的高导电性柔性层的可行性，该阵列可用于驱动电致发光(EPD)和有机发光二极管(OLED)显示器。这将利用基于石墨烯的油墨作为当前使用的昂贵金属的经济高效的替代品，并将展示在工业环境中生产石墨烯的可制造性和可扩展性。油墨将采用高石墨烯含量(&gt；10g/L)配制，以获得所需的导电性和可加工性，适用于各种印刷技术(棒材涂布、喷墨印刷和柔版印刷)，用于驱动EPD和OLED的灵活ActiveMatrix阵列。将石墨烯集成到灵活的有源矩阵阵列中，将展示石墨烯在实现一系列可折叠消费电子应用方面的潜力。

Graphene's unique properties make it ideal for a variety of applications, in particular for ultraflexible electronic devices,such as displays, touch screens, e-papers, smart packaging and smart textiles. These require flexible conductive films aselectrodes and interconnections, and metallic films or grids are currently used as back planes in displays and touchscreens. However, in addition to being expensive, these are environmentally unstable, brittle and not fully flexible (e.g.conformable). Graphene as a flexible conductive layer could underpin plastic electronics advantages of low temperatureprocessing, printing flexibility and lower cost manufacturing. This project aims to demonstrate the viability of graphene as ahighly conductive flexible layer in a flexible active matrix array that can be used to drive Electrophoretic (EPD) and OrganicLight Emitting Diode (OLED) displays. This will exploit graphene based inks as a cost-effective replacement of currentlyused expensive metals, and will demonstrate the manufacturability and scalability of the production of graphene in anindustrial context. Inks will be formulated with high loading of graphene (>10g/l), to achieve the required conductivity andprocessability for a variety of printing technologies (bar coating, ink-jet printing and flexographic printing) for flexible activematrix arrays that can be used to drive EPDs and OLEDs. Integrating graphene in a flexible active matrix array will showthe potential for graphene in enabling a range of foldable consumer electronics applications.
