采用对苯二酚添加剂对六方氮化硼（h-BN）水溶液进行等离子体处理，并通过zeta电位分布分析对苯二酚添加剂的影响。对苯二酚添加剂增强了溶液中的等离子体修饰，产生了分散良好的h-BN颗粒，通过离心分离。在中性状态下，平均电位提高到-50 mV，并保持在6-9的pH范围内。红外吸收光谱表明，溶液中的等离子体对分散的h-BN粒子进行了羟基官能团修饰。
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.
