Abstract
A method of preparing a graphene circuit pattern, a substrate and an electronic product are disclosed. The method of preparing a graphene circuit pattern includes: immersing a metal circuit pattern in a graphene oxide solution to cause a redox reaction between the metal circuit pattern and graphene oxide, thereby forming the graphene circuit pattern. The graphene circuit pattern may be directly formed at a location of the metal circuit pattern, and is simple in production process, low in cost, and suitable for mass production.
