摘要：
The present invention relates to a method of preparing an at least partially transparent and conductive layer (22) comprising graphene, the method comprising the steps of: (a) applying a dispersion comprising graphene oxide onto a substrate to form a layer comprising graphene oxide on the substrate, and (b) heating at least part of the layer obtained in step (a) by laser irradiation (34) at a laser output power of at least 0.036 W, thereby chemically reducing at least a part of the graphene oxide to graphene (33) and physically reducing the thickness of the layer by ablation. An advantage of the present invention is that it provides a simplified method of preparing a layer comprising graphene. The layer thus prepared has desirable transparency and conductivity.
摘要（中）：
本发明涉及一种制备包括石墨烯的至少部分透明和导电层（22）的方法，所述方法包括以下步骤：（a）将包含氧化石墨烯的分散体施加到基底上以形成包含氧化石墨烯的层 基板，和（b）通过激光照射（34）以至少0.036W的激光输出功率加热在步骤（a）中获得的层的至少一部分，从而化学还原至少一部分氧化石墨烯到石墨烯 （33），并通过消融物理地减小层的厚度。 本发明的优点在于其提供了制备包含石墨烯的层的简化方法。 由此制备的层具有期望的透明度和导电性。
