This Small Business Innovation Research (SBIR) Phase I project aims to demonstrate technical feasibility of producing low-cost, high-quality and large-area graphene films. The approach is to grow uniform graphene films over continuous tapes of electropolished catalytic copper foil in a roll-to-roll process. This project is expected to address critical challenges that limit industrial manufacture of graphene films including, (1) the need for high vacuum and high temperature, resulting in high cost; and (2) the limitation of graphene film size by the furnace dimension. The broader/commercial impact of this project will be the potential to provide high-quality wafer-scale graphene material in industrial quantities. The technology will have advantages of cost, quality, and design flexibility over competing concepts. Large-area graphene films can be used for industrial applications including flexible, transparent electrode, Radio-Frequency electronics, Field-Effect-Transistor-based chemical sensors, near infrared detectors, as well as academic applications such as novel sample supports for ultra-high resolution transmission electron microscopy.

这个小企业创新研究（SBIR）一期项目旨在证明生产低成本、高质量和大面积石墨烯薄膜的技术可行性。该方法是在连续的电抛光催化铜箔带上以卷对卷的方式生长均匀的石墨烯薄膜。该项目有望解决限制石墨烯薄膜工业生产的关键挑战，包括：(1)对高真空和高温的需求，导致高成本；(2)石墨烯薄膜尺寸受炉膛尺寸的限制。该项目的更广泛/商业影响将是提供高质量的工业批量晶圆级石墨烯材料的潜力。与竞争概念相比，该技术在成本、质量和设计灵活性方面具有优势。大面积石墨烯薄膜可用于工业应用，包括柔性透明电极，射频电子，基于场效应晶体管的化学传感器，近红外探测器，以及学术应用，如超高分辨率透射电子显微镜的新型样品支架。
