将石墨烯有效可靠地转移到感兴趣的基底上是石墨烯合成和应用之间的关键桥梁。这个问题尚未完全解决的主要原因是在转移过程中使用聚合物介质来保护单原子厚度的材料。在这里，我们展示了一种通用的和可扩展的方法，将化学气相沉积的石墨烯转移到任意表面上，而不需要任何聚合物，这将产生宏观和微观清洁，连续和均匀的石墨烯样品转移到各种各样的衬底上，以及可扩展的逐层石墨烯外延结构。此外，与传统方法相比，转移的石墨烯在电导率方面表现出总体100%的增强，从而可以展示各种高性能柔性透明电极。我们相信，这种新的转移技术将为下一代柔性电子产品和其他基于石墨烯的颠覆性技术的工业化提供机会。
An efficient and reliable transfer for graphene onto the substrates of interests acts as the crucial bridge between the graphene synthesis and applications. The main reason that this issue has not been fully addressed is the use of a polymer medium to protect the one-atom-thick material during the transfer process. Here we demonstrate a general and scalable method to transfer chemical-vapor-deposited graphene onto arbitrary surfaces without any polymers, which yields the transfer of macroscopically and microscopically clean, continuous and uniform graphene samples onto a wide variety of substrates, as well as the scalable layer-by-layer graphene epitaxial structures. Moreover, the transferred graphene exhibits an overall 100% enhancement in the electrical conductivity compared with the conventional method, so that various high-performance flexible transparent electrodes can be demonstrated. We believe that this new transfer technique will offer the opportunities to the industrialization of next generations of flexible electronics and other graphene-based disruptive technologies.
