Surface study of hexagonal boron nitride powder by diffuse reflectance Fourier transform infrared spectroscopy

摘要

The surface chemistry of hexagonal boron nitride powder is examined. Surface functional groups are found to consist of a mixture of primary and secondary amine groups as well as hydroxyl groups. The surface has a net basic character indicating that the amine contribution to the overall surface chemistry is greater than that of the acidic hydroxyl contribution. A chemical surface treatment also is performed to modify the surface chemistry of hexagonal boron nitride powder. Copyright (c) 2005 John Wiley & Sons, Ltd.
