Micro-patterns of reduced graphene oxide (RG-O) platelets crafted by a self-assembled template

Abstract

Highly ordered reduced graphene oxide (RG-O) micro-patterns were crafted by an efficient method capitalizing on the self-assembled polymer template. Central to this strategy is to fabricate the polymer template over a large area via controlled evaporative self-assembly (CESA), and treat the templated glass substrate with the O-2 plasma to render the favorable interaction between the RG-O platelets and the substrate, thereby yielding well-defined microscopic RG-O patterns on the large scale.
