采用水热法合成油酸修饰的硼酸镧纳米棒(OA/LaBO3·H2O)，利用X射线衍射和扫描电镜等测试技术对其微观结构进行表征，并在四球摩擦试验机上考察其在菜籽油中的摩擦磨损性能。结果表明，所制备的OA/LaBO3·H2O为直径约50 nm、长达500 nm的疏水性纳米棒。OA/LaBO3·H2O能显著提高菜籽油的抗磨减摩性能；当OA/LaBO3·H2O的添加量为1%(质量分数)时，菜籽油的抗磨减摩性能最佳。

Oleic acid (denoted as OA) surface-caped lanthanum borate nanorods, abbreviated as OA/LaBO3·H2O, were prepared via hydrothermal method. The microstructures of the as-prepared OA/LaBO3·H2O nanorods were characterized by X-ray diffraction (XRD) and scanning electron microscopy (SEM) techniques. The friction and wear properties of OA/LaBO3·H2O nanorods in rapeseed oil were evaluated with a four-ball tribo-tester. The results show that the as-prepared OA/LaBO3·H2O nanorods are hydrophobic and display nanorods morphology with uniform diameter of about 50 nm and length of up to 500 nm. In the meantime, OA/LaBO3·H2O nanorods can obviously improve the anti-wear and friction-reducing capacities of rapeseed oil, and the optimal anti-wear and friction-reducing properties of rapeseed oil were obtained at an OA/LaBO3·H2O content of 1% (mass fraction).
