Hyperbranched Cyclotriphosphazene Polymer-grafted Graphene with Amphipathicity

Grafting of hyperbranched cyclotriphosphazene polymer(HBP) onto reduced graphene oxide (HBP-RGO) surface wasachieved by the repeated reactions between the chlorine groupsof hexachlorocyclotriphosphazene and the amino groups ofhexamethylenediamine. FTIR and XPS analyses showed thathyperbranched cyclophosphazene-grafted graphene had beensuccessfully prepared&#..
