当金刚石颗粒用作磨料剂时，它们必须均匀分散。因此，人们开发了许多分散剂来改善磨料的分散性能。然而，使用分散剂改善磨料的表面性能是不必要的。我们尝试了一种内在表面改性的金刚石颗粒用作磨料的超声波曝光。证实了超声暴露对zeta电位的影响。得到了平均尺寸小于0.1µm的亚微米级金刚石颗粒。
When diamond particles are used as abrasive agents, they have to disperse homogeneously. Consequently, many dispersants have been developed to improve the dispersion property of abrasive agents. However, improvement of surface properties of abrasive agents using dispersants is not essential. We attempted an intrinsic surface modification of diamond particles used as abrasive agents by ultrasound exposure. The change of zeta potential by ultrasound exposure was confirmed. Sub-micron diamond particles with average size smaller than 0.1 µm were obtained.
