A METHOD OF PRODUCING A GRAPHENE LAYER |
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. |
