Abstract

original image

Water-soluble magnetic-functionalized reduced graphene oxide nanocomposites can be easily prepared by an in situ high-temperature decomposition of iron precursor in liquid polyols (see image). This new class of graphene sheets decorated with magnetic nanoparticles verifies the feasibility to use graphene as supports to drive the development of carbon-based composite nanomaterials.
