| 摘 要： | 采用原位合成的方法合成了硫化铜纳米微粒,通过静置及高低速离心测试,证明硫化铜纳米微粒在基础油石蜡中具有良好的分散稳定性。TEM研究证明合成的纳米颗粒粒径约为20 nm。通过FT-IR表征合成样品,发现油酸分子-COOH部分和硫化铜表面发生了化学性吸附,增强了硫化铜纳米微粒在基础油中的油溶性。用高速环-块磨损机考察了含硫化铜颗粒的基础油的摩擦学性能,发现添加有油酸修饰的硫化铜纳米颗粒有显著的抗磨减摩效果。

| Abstract: | CuS nanoparticles was prepared by the method of in-situ surface modification.Centrifugal tests showed that the nanoparticals had good dispersion stability.TEM image confirmed that the average diameter of the CuS nanoparticles was about 16nm.FT-IR study demonstrated that the surface of CuS nanoparticles combined with carboxyl group of oleic acid through chemical absorption.This lead to a great improved oil-soluble ability via using the organic modification on the surface of CuS nanoparticles in liquid paraffin.The friction reduction and antiwear behaviors of the prepared oleic acid modified Cu nanoparticles as oil additives in liquid paraffin were evaluated with four-ball wear test machine.The result showed that oleic acid modified CuS nanoparticles had a good antiwear and friction reduction properties in liquid paraffin. |
