Boron Nitride Exfoliation

Our research on hexagonal boron nitride is about functionalization and composites of boron nitride nanosheets (BNNS). Hexagonal boron nitride is the isoelectric analogue of graphite. We are focusing on having it functionalized and exfoliated, to produce BNNS. A method of chemical functionalization has been developed to obtain good solubility in solvent and prominent interactions between a polymeric matrix and BNNS fillers. After that composites with high thermal conductivity, good mechanical properties, and low coefficient of friction can be fabricated.
