▎ 摘　　要

"Graphene paper" prepared by new proprietary method involving high pressure and high temperature treatment in the reduction process show new possibilities in this area. Different phase content: multilayer and single layer graphene stacks recorded in this study for RGO samples are accompanied by the specific electric and optical parameters. We have found that process temperatures above 900 degrees C play crucial role in structural and other properties. For the process temperature around 2000 degrees C we found the onset of the graphitization in the samples.
