介绍了一种制备具有良好抗氧化性的疏水性纳米铜颗粒的新化学工艺。在水/有机溶液中得到了分散性良好、表面性质良好的纳米铜颗粒。在这个过程中，油酸既起到了相转移剂的作用，又起到了粒子保护剂的作用，协调了它们在新生成的铜粒子表面的羧基末端，油酸的疏水碳尾从粒子表面向外指向。此外，这种有机薄膜对防止新生成的铜颗粒氧化也起到了重要作用。
A novel chemical process for producing hydrophobic nanocopper particles with satisfied antioxidation property is described here. Well-dispersed nano-copper particles with satisfied surface properties were obtained from the water/organic solution. In this process, oleic acid acts as both a phase-transfer agent and a particle protector coordinating their carboxyl end groups on the newly generated copper particles surface, and the hydrophobic carbon tails of the oleic acids are pointed outwards from the surface of particles. In addition, this organic film also plays an important role for preventing the newly generated copper particles from oxidation.
