Functionalized graphene nanomaterials: new insight into direct exfoliation of graphite with supramolecular polymers

Nanoscale. 2016 Jan 14;8(2):723-8. doi: 10.1039/c5nr07076g.

Abstract

A novel urea-cytosine end-capped polypropylene glycol (UrCy-PPG) can self-assemble into a long-range ordered lamellar microstructure on the surface of graphene, due to the strong specific interactions between UrCy-PPG and graphene. In addition, the graphene composite produced exhibits a high conductivity (∼1093 S m(-1)) with a dramatic thermo-responsive ON/OFF resistance-switching behavior (10 consecutive cycles).
