A novel approach of patterning graphene on conductive surfaces based on local electrochemical reduction of graphene oxide is reported. Graphene is "written" from typical graphene oxide dispersion by applying negative potential on conductive surfaces vs. a micrometer-sized counter electrode "pen" with scanning electrochemical microscopy (SECM). Micrometer scaled patterns are successfully generated on gold and stainless steel surfaces.
本文报道了一种在导电表面上基于局部电化学还原氧化石墨烯来图形化石墨烯的新方法。通过在扫描电化学显微镜（SECM）中在导电表面上施加相对于微米级对电极“笔”的负电势，从典型的氧化石墨烯分散体中“书写”石墨烯。成功地在金和不锈钢表面上生成了微米级的图案。
