摘要： 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 (101, 201) in a graphene oxide solution (1020, 2020) to cause a redox reaction between the metal circuit pattern (101, 201) and graphite oxide, thereby forming the graphene circuit pattern (102, 202). 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.
