▎ 摘　　要

We present a versatile technique to create three dimensional graphene oxide (GO)-reduced GO (rGO) stacked-layered structure with the added attribute that micropatterns could be defined in each layer. We used focused laser beam to convert GO to rGO and create micropatterns of rGO on a heated substrate with GO spin-coated on it. The sample was then sonicated. Either the (1) micropatterned rGO (laser scanned region) or (2) micropatterned GO (unscanned region) could be preferentially removed depending on laser power and temperature of the substrate. A new layer of GO was then spin-coated and thus achieving 3D multilayered and patterned structure. (C) 2012 American Institute of Physics. [http://dx.doi.org/10.1063/1.4752752]
