This study evaluated the formation of rolled hexagonal boron nitride nano-sheets (h-BN nanoscrolls) on their unique morphology, magnetic properties and applications. We describe a novel way to insert a desired material into BN nanoscrolls, where the inner-tube diameter can be controlled. By carefully selecting a Lewis base and the reaction conditions, the approach might be useful for the preparation of complexes of hexagonal boron nitride nanoscrolls and other materials. More interestingly, we demonstrate a method of tailoring magnetic nanocomposites through hybridization with magnetic nanomaterials, including the use of hexagonal boron nitride templates. Boron nitride nanosheets exhibited a typical diamagnetism, but the magnetic susceptibility of rolled-up boron nitride sheets showed para-magnetism. The zero-field-cooled curve for h-BN scrolls decorated with Fe3O4 nanoparticles (NPs) exhibited an apparent rounded maximum blocking temperature (TB) at 192 K, which is a dramatic increase in TB compared with Fe3O4 NPs. These magnetic nano-scroll derivatives are remarkable materials and should be suitable for high-performance composites and nanoscale, medical, and electromechanical devices.
