The investigation of BN nanosheets production by using solvent exfoliation



  1. Firat University, Vocational School of Technical Sciences, Department of Machine and Metal Technology, Elazığ, Turkey


In this study, Boron Nitride Nanosheets (BNNSs) were produced via solvent exfoliation method with hexagonal boron nitride (h-BN) which was used as the raw material. This method is essentially based on separating the layers , which are bound with weak bonds, through a solvent. For this purpose, h-BN powders were firstly exposed to an acidic process and then heat treatment. A new structure with expanded hexagonal layers (expanded hexagonal boron nitride) was obtained at the end of this process. Synthesized expanded hexagonal boron nitride was sonicated in a solvent (N,N dimethylformamide). At the end of the process, synthesized samples were characterized by Scanning electron microscope (SEM), Transmission electron microscope (TEM), UV-Vis absorption spectra, Fourier transform infrared (FTIR) and atomic force microscope (AFM). Consequently, it was found that BNNS layers that had a thickness of several nanometers and a width of a few hundreds of nanometers were produced..
