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.
