Abstract

Abstract: Plasma processing in a solution with a hydroquinone additive was performed for the aqueous dispersion of hexagonal boron nitride (h-BN), and the effect of the hydroquinone additive was determined by analyzing the zeta potential distribution. The hydroquinone additive enhanced plasma modification in the solution to produce well-dispersed h-BN particles separated by centrifugation. The mean zeta potential improved up to −50 mV at neutrality and maintained in a pH range of 6–9. Infrared absorption spectra suggested that the dispersed h-BN particles were modified with hydroxyl functional groups by plasmas in the solution.
