The development of 2D nanosheets in stable suspension that respond rapidly to and can be manipulated by applied magnetic fields may become highly desired, for instance extractions. Here we report the efficient and unique approach of decoration of 2D clay nanosheets in liquid suspension with magnetic nanoparticles only in one side. Superparamagnetic iron oxide nanoparticles were used to functionalize insulating transparent synthetic sodium fluorohectorite clay nanosheets with aspect ratio of about 20,000. The nanoparticle density on the nanosheets are tuned to different coverage fractions. Small Angle X-ray Scattering (SAXS), spectroscopy (FTIR, UV-VIS), microscopy techniques (SEM and AFM), and magnetic properties were used to characterize the magnetic nanosheets. This new material opens new possibilities of scalable applications.
