Coupling Graphene Sheets with Iron Oxide Nanoparticles for Energy Storage and Microelectronics

Abstract

In this report we summarize our studies into a group of pyrene-spacer-dopamine (PyDop) ligands capable of noncovalently coupling superparamagnetic y-Fe2O3 magnetic nanoparticles (MNP) to grapheme-based materials. The distance of the ligands to the graphene derivative surface can be varied by changing the spacer length. This project has been successful in the demonstration of high density coupling of PyDop functionalized MNPs onto different types of graphene materials like reduced graphene oxide (rGO) nanoplatelets, chemically reduced graphene as well as electrochemically exfoliated graphene. Some early results demonstrating the applicability of reduced graphene oxide-PyDop- y-Fe2O3 as a charge trapping layer in memory transistors are also presented.
