▎ 摘　　要

NOVELTY - The method involves prereducing graphite oxide (A). The prereduced graphite oxide is set (B) on a substrate. The substrate having the graphite oxide set to form graphene is laser-reduced (C). USE - Method for preparing a graphene, a graphene electrode and a graphene super capacitor. ADVANTAGE - The method enables reducing prereduced graphite oxide more easily into graphene through laser-reducing as the graphite oxide has prereduced in a certain degree prior to the laser reduction, where the reducing effect of graphene is obtained from the prereduced graphite oxide film after photoetching is evidently superior to that of the graphene prepared without prereduction treatment such that the time of laser reduction can be apparently decreased and production efficiency can be improved. DESCRIPTION OF DRAWING(S) - The drawing shows a flow diagram illustrating a method for preparing a graphene, a graphene electrode and a graphene super capacitor.'(Drawing includes non-English language text)' Step for prereducing graphite oxide (A) Step for setting prereduced graphite oxide (B) Step for laser-reducing substrate having the graphite oxide set to form graphene (C)
