▎ 摘 要
NOVELTY - An oxide graphene sol and metal salt solution and/or metal colloidal solution is applied on a substrate layer, and separated to form solid film. The obtained solid film is treated at 30 seconds to 10000 hours in hydrogen atmosphere or reducing atmosphere containing hydrogen at -50 degrees C to 200 degrees C and pressure of 0.01-100 MPa, to obtain graphene-type conductive material. USE - Preparation of graphene-type conductive material. The preparation occurs at a low temperature using cheap hydrogen, so it's simple and environmental friendly DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for graphene-type conductive material.
