Abstract
A method for preparing a graphene based conductive material and the graphene based conductive material prepared by the method. The method includes: preparing a solid film on a substrate layer by using graphene oxide sol and metal salt solution and/or metal colloidal solution, keeping the solid film separated or without separated from the substrate layer standing for from 30 s to 10000 h in an atmosphere consisting of hydrogen or containing hydrogen with temperature of −50° C.˜200° C. and hydrogen pressure of 0.01-100 MPa, obtaining the graphene based conductive material. The preparation method can be processed at low temperature and uses cheap hydrogen as reductant, so the preparation process is simple and environment friendly.
