| Abstract: |
| Graphene, a well-known two-dimensional (2D) material, has sparked broad enthusiasm in both scientific and industrial communities in these years, due to its exceptional electrical, thermal, mechanical, and versatile properties. However, many properties and applications of graphene are layer-number dependent. The preparation of high-quality graphene with controlled layer numbers is full of challenge, since the layer number varies much with the synthesis routes and relevant experimental conditions. Hence, there is an urgent need to improve the layer-number controllability of graphene preparation. Generally, graphene can be prepared by two complementary approaches: “top-down” and “bottom-up”. Since they have their own advantages, the recent advances in the layer-number tunable preparation of high-quality graphene are separately studied from the two aspects in this review, especially those dedicated to single parameter. Some effective strategies are discussed in detail, mainly including 1) supercritical-CO2 assisted sonication, electrochemical exfoliation of graphite intercalation compounds, and layer-by-layer thinning with plasma or laser, for “top-down” graphene; 2) chemical vapor deposition (CVD) on dual-metal substrate, ion-implantation CVD, layer-by-layer CVD, plasma-enhanced CVD, layered-double-hydroxides template-assisted CVD; and 3) graphite-enclosure assisted epitaxial growth and pulsed-magnetron-sputtering assisted physical vapor deposition for “bottom-up” graphene on various substrates. In addition, the respective advantages of graphene with different layer numbers in properties and applications are also presented. Finally, the contribution concludes with some important perspectives on the remained challenges and future perspectives. |

| 综述：高质量层数可控石墨烯的制备与广泛应用 谢允斌1,2,3，黄美荣1,2，李新贵1,2* (1.同济大学 环境科学与工程学院，污染控制与资源化研究国家重点实验室，上海市污染控制与生态安全研究院，上海 200092; 2.同济大学 材料科学与工程学院，先进土木工程材料教育部重点实验室，上海 200092; 3.上海维凯光电新材料有限公司,上海 201111) 中文说明：作为一种新兴并受到学术研究与工业开发界广泛关注的二维材料，石墨烯具有出色的电学、热学与机械性能，但这些特性实际上与其层数直接相关。目前基于常用的两大类石墨烯的制备方法——无论是基于“自上而下”剥离的液相剥离法、还是基于“自下而上”合成的化学气相沉积（CVD）与外延生长法，实际上得到的大都是不同层数石墨烯的混合物。由于石墨烯的层数影响因素众多，且随其制备方法各不相同，因此如何制备具有不同层数且分布均匀的石墨烯极具挑战性。为此，本文综述了制备层数可控石墨烯的研究进展，重点基于上述两大类方法介绍了一些提高层数可控性的有价值的制备方法，如“自上而下”方法中的超临界二氧化碳辅助超声液相剥离、等离子体或激光逐层减薄，以及“自下而上”方法中的离子注入CVD、等离子体增强CVD等。分析了这些方法的策略、机理，评价了其层数可控性及所制备石墨烯的质量，指出了其优点与局限性。此外，总结了不同层数石墨烯的性能特征与广阔应用潜力。最后，展望了层数可控的高质量石墨烯科学研究与工业技术开发的美好前景与面临的诸多挑战。 关键词：石墨烯，纳米片制备，可控层数，可调控形貌，高质量石墨烯 |
