Electrodes for Large Area Electronics Based on Partially Oxidized Graphene

大面积电子产品的概念建立在方便的溶液处理和廉价的原材料基础上。为此，该项目有两项主要的技术任务。在第一个任务中，我们打算彻底表征和优化一种具有优异光学和电学性能的新型可溶液处理的石墨烯。在第二个任务中，我们打算演示一种简单的图案化方法，用于集成到大面积有机电子中。这项提议的智力价值来自其材料科学的影响？一种透明的、灵活的、可溶液处理的、容易实现为各种有机电子器件的通用电极的现实材料尚未得到证明。拟议项目的更广泛影响来自快速切换和低功耗电子产品的社会影响，这些电子产品价格低廉，将是巨大的。大面积电子产品被广泛用于各种消费设备中，使用简化的石墨烯电极可能会导致设备更多地处于待机状态，节省能源并延长电池寿命。该计划的教育目标是为本科生提供研究经验，为K-12教师提供可在学校演示的实验室模块，并参与清洁能源纳米技术IGERT计划的丰富活动(主任是该计划的PI)。此外，还计划与伦敦帝国理工学院开展积极的国际合作。

The concept of large area electronics builds on facile solution processing and inexpensive raw materials. Towards this end, the project has two primary technical tasks. In the first task, we intend to thoroughly characterize and optimize a novel form of solution processable graphene that has superior optical and electrical properties. In the second task, we intend to demonstrate a facile patterning method for integration into large area organic electronics. The intellectual merit of the proposal arises from its materials science impact ? a realistic material that is transparent, flexible, solution processable and can be readily implemented as universal electrodes in a variety of organic electronics devices has yet to be demonstrated. The broader impacts of the proposed project arise from the societal impact of a fast switching and low power consuming electronics that are inexpensive will be tremendous. Large area electronics are used in wide ranging consumer devices and the use of reduced graphene electrodes could lead to devices that would encourage more standby operations, save energy and extend battery life. The educational goals of this proposal are to provide research experience for undergraduates, provide laboratory modules for K ? 12 teachers that can be demonstrated in schools, and to participate in the enrichment activities of the Nanotechnology for Clean Energy IGERT Program (Director is the PI of this proposal). In addition to the above, an active international collaboration is planned with Imperial College London.
