- Abstract
- Controlling tunable properties by rolling up two dimensional nanomaterials is an exciting avenue for tailoring the electronic and magnetic properties of materials at the nanoscale. We demonstrate the tailoring of a magnetic nanocomposite through hybridization with magnetic nanomaterials using hexagonal boron nitride (h-BN) templates as an effective way to evolve magnetism for the first time. Boron nitride nanosheets exhibited their typical diamagnetism, but rolled-up boron nitride sheets (called nanoscrolls) clearly have para-magnetism in the case of magnetic susceptibility. Additionally, the Fe3O4 NP sample shows a maximum ZFC curve at about 103 K, which indicates well dispersed superparamagnetic nanoparticles. The ZFC curve for the h-BN-Fe3O4 NP scrolls exhibited an apparent rounded maximum blocking temperature at 192 K compared to the Fe3O4 NPs, leading to a dramatic increase in TB. These magnetic nanoscroll derivatives are remarkable materials and should be suitable for high-performance composites and nano-, medicaland electromechanical-devices.
