Size Fractionation of Graphene Oxide Sheets via Filtration through Track-Etched Membranes

By Ji Chen, Yingru Li, Liang Huang, Naer Jia, Chun Li, Gaoquan Shi
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 here can be used for the performance improvement of graphene-based materials.
