Graphene with high surface roughness graphene sheet and manufacturing method thereof

摘要

The present invention provides a method for producing a graphene oxide film, comprising the steps of: preparing a dispersion solution containing graphene oxide; Adding an amine to the prepared dispersion solution to prepare a mixed solution containing graphene oxide in which other functional groups other than the carboxyl groups present in the graphene oxide are selectively reduced; And reducing the prepared mixed solution. The present invention also relates to a method for producing graphene.In the method for producing graphene according to the present invention, other functional groups other than the carboxyl groups present in graphene oxide are selectively reduced by amine addition, so that graphene having high conductivity with low surface roughness can be produced.
