Although　graphene　has　excellent　properties,　it　does　not　mean　that　all　graphene-based　devices　will　have　high　performance.　Even　though　three-dimensional　(3D)　porous　graphene　are　believed　to　be　of　great　importance　in　many　applications,　the　control　of　the　microstructures　and　properties　of　this　material　to　meet　different　application　requirements　in　industrial　practice　remains　challenging.　In　this　report,　we　proposed　a　facile　approach　to　tune　the　mophology　and　electrical　conductivity　of　porous　graphene　during　the　laser-induced　polyimide　(PI)　graphitization　process.　This　porous　graphene　with　mesoporous　and　macroporous　has　a　large　specific　surface　area,　extremely　low　densities　and　good　conductivity.　Our　results　demonstrate　a　practical　method　to　adjust　structures　and　properties,　and　further　benefit　the　various　applications　of　porous　graphene.　This　research　also　provides　a　promising　candidate　for　porous,　high　performance　and　low-cost　materials　in　the　effective　use　of　energy　storage　systems.
