Preparation and Superparamagnetic Properties of graphene/Fe3O4 nanocomposite
The superparamagnetic graphene/Fe3O4 nanocomposite has been successfully prepared via an easy and scalable chemical precipitation method.High quality graphene sheets were prepared from natural flake graphite by oxidation, rapid expansion and ultrasonic treatment.The structure of graphene and graphene/Fe3O4 nanocomposite was investigated by transmission electron microscopy, X-ray diffraction and Fourier transform infrared spectroscopy.The graphene sheets possess a curled morphology consisting of a thin wrinkled paper-like structure.The graphene/Fe3O4 nanocomposite exhibits a superparamagnetic behavior, its specific saturation magnetization, Ms is 38.92 emu g-1.
