Fullerene-regulated graphene oxide nanosheet membranes with well-defined laminar nanochannels for precise molecule sieving

Abstract

Graphene oxide nanosheet membranes with well-defined laminar nanochannels were constructed using functionalized fullerene as a nano-spacer and a crosslinker. The resultant membranes retain good hydrophilicity and have short laminar channels with precise <italic>d</italic>-spacing from 0.91 to 1.56 nm and excellent sieving selectivity for organic dyes.
