Abstract
A method for preparing a graphene composite membrane on the surface of a tubular support. In the method, a tubular ceramic membrane is used as the support, a layer of graphene material is uniformly prepared on the surface of the support by vacuum suction, and the defect-free tubular graphene composite membrane is obtained by the drying process.
