The invention provides a preparation method of a graphene composite film with a conducting circuit on a surface. The preparation method comprises the following steps: firstly forming a conducting circuit on the surface of a first substrate to obtain the substrate material; compounding a layer or multi-layer graphene film on the surface with the conducting circuit of the substrate material obtained in above-mentioned step, and then combining a second substrate on the surface of the graphene film to obtain an intermediate product; finally removing the first substrate of the above-mentioned intermediate product by using the chemical etching method to obtain the graphene composite film with the conducting circuit. A high-conducting patter can be formed on the graphene film surface by using the preparation method disclosed by the invention, and the shape of the formed high-conducting pattern is random, especially, the binding force between the conducting circuit and the graphene film is good, and the high-conducting pattern has the good flexibility. Meanwhile, the preparation method provided by the invention is not only simple and practicable in process procedure, but also can match with the process procedure of the graphene film, and is suitable for the large-scale industrial application.
