Abstract

Graphene oxide (GO) fractionation is achieved by size-exclusive passing of GO sheets through size-defined pores of track-etched membranes, which separate the GO sample into three portions with narrow size distributions. The method reported can be used for the performance improvement of graphene-based materials.

Keywords: filtration; graphene oxide; size fractionation; track-etched membranes.
