项目摘要

Graphene is a one atom thick sheet of conductive carbon. For a given surface area, it is the lightest weight electronic conductor of any material and can be produced relatively inexpensively, and in large volume, from natural graphite - a resource for which Canada holds the only significant source in North America and the 5th largest supply globally. This leads to its potential use in a multitude of applications for improved energy storage, energy generation or even as an advanced membrane material for separations. Unfortunately, very few commercial technologies involving graphene-based materials have emerged, in large part due to the difficulty in processing these 2D sheets into useful, 3D materials with predicable structure and thus function.*** To address this challenge, this research program aims to develop new tools and processes to create a platform of graphene-based materials whose structure can be manipulated and fine-tuned at the nanoscale. This will be achieved by developing coating processes capable of depositing large-area monolayer graphene films onto a variety of substrates. These approaches will take advantage of the fact that graphene-based sheets can float on water supported by the same forces that allow a water spider to walk on water. Through the development of this coating approach, atomically thin sheets (of a large area) will be built up layer-by-layer to create fully dense multi-layer films. In order to introduce useful space between each layer, we will develop coating approaches to decorate graphene with molecular scale pillars of tunable size which will define the effective pore opening between sheets in the layer-by-layer composites. Depending on the engineered pore-size, these materials could exhibit properties ranging from completely blocking layers (i.e., zero porosity) for advanced packaging, to more energy efficient membranes for water purification, and finally with the ability to accommodate ions and active material coatings for advanced supercapacitors, batteries or electrocatalysts.*** This research program is also designed to foster and inspire highly qualified personnel through a combination of apprenticeship, mentorship and exposure to an exciting but rigorous research environment. Specific activities proposed throughout this research program will build a foundation for many eventual application areas which will translate to new products for Canadian companies or to completely new ventures. The use of graphene in high volume applications such as in Li-ion batteries, supercapacitors and large area membranes for separations are expected to stimulate Canada's graphite economy leading to new jobs and exports.**
石墨烯是一个原子厚的导电碳片。对于给定的表面积,它是任何材料中重量最轻的电子导体,并且可以相对便宜地大量生产天然石墨-加拿大是北美唯一的重要来源,也是全球第五大供应国。这导致其在许多应用中的潜在用途,用于改善能量储存,能量产生,甚至作为先进的分离膜材料。不幸的是,涉及石墨烯基材料的商业技术很少出现,这在很大程度上是由于难以将这些2D片材加工成具有可预测结构和功能的有用的3D材料。为了应对这一挑战,该研究计划旨在开发新的工具和工艺,以创建一个石墨烯基材料平台,其结构可以在纳米级进行操纵和微调。这将通过开发能够在各种基底上沉积大面积单层石墨烯膜的涂层工艺来实现。这些方法将利用这样一个事实,即石墨烯基片可以漂浮在水上,由允许水蜘蛛在水上行走的相同力支撑。通过这种涂层方法的发展,原子级薄片(大面积)将逐层构建,以创建完全致密的多层膜。为了在每层之间引入有用的空间,我们将开发涂层方法来用可调尺寸的分子尺度柱来装饰石墨烯,这将在逐层复合材料中限定片材之间的有效孔隙开口。根据设计的孔径,这些材料可以表现出从完全阻挡层(即,零孔隙率)用于先进包装,到用于水净化的更节能的膜,最后能够容纳先进超级电容器、电池或电催化剂的离子和活性材料涂层。*该研究计划还旨在通过学徒,导师和接触到一个令人兴奋但严格的研究环境相结合,培养和激励高素质的人才。在整个研究计划中提出的具体活动将为许多最终的应用领域奠定基础,这些应用领域将转化为加拿大公司的新产品或全新的企业。石墨烯在锂离子电池、超级电容器和大面积分离膜等大批量应用中的使用,预计将刺激加拿大的石墨经济,从而带来新的就业机会和出口。
