▎ 摘　　要

NOVELTY - Perforating graphene involves: exposing a stream of gas into plasma to generate an activated gas stream; directing the activated gas stream toward a graphene sheet; and perforating the graphene sheet with the activated gas stream. USE - For perforating graphene (claimed), which is used as fluid/gas filters. ADVANTAGE - The present method allows the number of holes and their size to be easily adjusted in graphene sheets. As a result, the graphene sheets are provided with holes that reliably allow the passage of certain nano-sized components while blocking other components. The process is also believed conducive for generating holes in graphene in a large scale manufacturing process.
