项目摘要

From the 1996 Nobel Prize for Chemistry, recognizing the synthesis of fullerene, to the 2010 Nobel Prize for Physics, awarded to the discovery of graphene, carbon-based materials have evolved into one of the hottest area in materials science. ***Differently from mainstream research in graphene, Fanchini's Laboratory of transparent, conducting, photo-active and carbon-based thin films, stemming from the Tier 2 CRC awarded to the PI, specializes in the synthesis, characterization and utilization of carbon-based thin films formed by PATCHWORKS of platelets of graphene or other carbon-based and organic nanomaterials, arranged like in jigsaw puzzles. Strong interest on these films stems from their ease of preparation by solution processing (which is uniquely suited for initiating to research HQP trainees in relatively small groups) and from their intriguing physico-chemical properties. Although many of such properties are reminiscent of individual graphene layers, a number of other concepts related to their NANOCOMPOSITE nature is required to design patchwork graphene films. Our transparent electrodes for flexible solar cells and LEDs have been taking unique advantages from our deeper understanding of the electro-optical properties of these films at the nanoscale. We also have been exploring devices based on their extreme thermal conductivity since our development of solution-processed graphene thin films of 2nd generation, as opposed to 1st generation graphene oxide-based films that were too rich in defects to enable thermal applications. After being instrumental in developing both 1st and 2nd generation of graphene thin films, Fanchini's Lab is now proposing new endeavors toward graphene-based thin films of 3rd generation, in which the application of nanoparticles and nanopores selectively modify the properties of each individual platelet. Such efforts will result in new devices, including the first prototype of energy-efficient and reversible graphene-based water filter. ***Nanoscale investigation of "patchwork" graphene thin films is uniquely facilitated when conducted in parallel with nano-optoelectronics instrument development. Stemming from Fanchini's recent development of the world-first three-dimensional scanning near-field optical technique, enabling educated design of nanoplasmonic solar cells, two new endeavors are here proposed: 1) nano-optical techniques for imaging photoexcitation in solar cells, either graphene-based or not, and 2) the first ever nano-thermo-optical techniques for imaging interfacial thermal resistivity, enabling graphene-based efficient thermal management in electronic devices.***These 5-year endeavors are instrumental to Fanchini's Lab longer term plans to use carbon-based nanomaterials and nano-optoelectronics to address Canada's demand for sustainable energy and to train the much needed, next generation of HQP in this area. ********

从1996年诺贝尔化学奖（诺贝尔化学奖）认识到富勒烯的综合，到2010年诺贝尔物理奖，授予了发现石墨烯的发现，碳材料已经演变为材料科学中最热门的地区之一。 ***与Fanchini的透明，指挥，光活动和基于碳的基于碳的薄膜实验室的主流研究不同，源自授予PI的第2级CRC，专门从事诸如基于碳或其他有机型碳和其他有机型碳组成的碳组成的碳基薄膜的合成，表征和利用。通过解决方案加工（非常适合在相对小组中研究HQP受训者）及其有趣的物理化学特性，对这些电影的植物易于制备（非常适合启动HQP受训者），对这些电影的植物植物的浓厚兴趣。尽管许多此类特性都想起了单个石墨烯层，但设计与纳米复合材料的性质相关的许多其他概念来设计拼布的石墨烯膜。我们对柔性太阳能电池和LED的透明电极已经从我们对纳米级这些膜的电光特性的更深入的了解中获得了独特的优势。自从我们开发了第二代溶液加工的石墨烯薄膜以来，我们还一直在基于其极端导热率探索设备，而与第一代基于氧化石墨烯的薄膜相比，这些膜过于富含缺陷以至于无法实现热应用。 Fanchini的实验室在开发第一代和第二代石墨烯薄膜方面发挥了作用后，现在提出了针对基于石墨烯的第三代薄膜的新努力，其中纳米颗粒和纳米孔的应用选择性地修改了每个单个血小板的性质。这样的努力将导致新设备，包括首个节能和可逆石墨烯的滤水器的原型。 ***与纳米 - 呼吸器仪器的开发并行进行时，“拼布”石墨烯薄膜的纳米级投资是独特的。来自Fanchini最近对世界上的三维扫描近场光学技术的发展，实现了纳米质太阳能电池的教育设计，这里提出了两个新的努力：1）纳米光学技术，用于在基于石墨烯基于石墨烯基于的nano-ever themials the nanano themial themial themial themitial themial themial the nanano-themitial themial themial the nanano-theref the nanano-theref the nanano-theref the nanano-theref the nanano-theref the nanano-theref tish。 ****这些5年的努力对Fanchini的实验室长期计划使用抗药性，从而使基于石墨烯的有效热管理有助于使用基于碳的纳米材料和纳米式电子产品来解决加拿大对可持续能源的需求，并在该领域培训了下一代HQP。 *******
