متن کاملGraphene-Based Membranes Fabricated Using High Purity Natural Vein Graphite (NVG)
The multilayer graphene oxide membranes (MGOMs) are fabricated using graphite oxide synthesized using a rare form of high purity natural vein graphite (NVG) and are characterized using FE-SEM, AFM and C 1s and O 1s core level photoemission (ESCA) for their properties. It is observed that NVG based MGOM can be thermally reduced energy efficiently to obtain graphene-like membranes. Keywords—graph...
