这个小型企业创新研究(SBIR)第一阶段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上以卷对卷的方式生长均匀的石墨烯薄膜。该项目预计将解决限制石墨烯薄膜工业化生产的关键挑战，包括：(1)对高真空和高温的需求，从而导致高成本；(2)石墨烯薄膜尺寸受炉子尺寸的限制。该项目的更广泛的商业影响将是有可能提供工业批量的高质量晶片规模的石墨烯材料。与竞争概念相比，这项技术将在成本、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、射频电子学、场效应管化学传感器、近红外探测器，以及用于超高分辨率电子显微镜的新型样品载体等学术应用。

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.
