In the present work, an efficient route has been further explored to achieve the batch synthesis of inorganic fullerene (IF)-WS2 nanoparticles, and the self-lubricating film is conveniently prepared by coating these nanoparticles on the surface of metal substrates. The as-synthesized IF-WS2 nanoparticles have a closed hollow structure with an average particle size of about 50 nm and are evenly distributed in the self-lubricating film. Further friction tests show that the film has excellent friction properties, with its lowest friction coefficient of approximately 0.008, which can be mainly attributed to the unique hollow cage structure and a smaller particle size of the IF-WS2 nanoparticles.

在目前的工作中，进一步探索了一种有效的途径来实现无机富勒烯（IF）-WS 2纳米颗粒的批量合成，并且通过将这些纳米颗粒涂覆在金属基底的表面上来方便地制备自润滑膜。合成后的IF-WS 2纳米颗粒具有封闭的中空结构，平均粒径约为50 nm，并均匀地分布在自润滑膜中。进一步的摩擦测试表明，该薄膜具有出色的摩擦性能，其最低摩擦系数约为0.008，这主要归因于独特的空心笼状结构和IF-WS 2纳米粒子的较小粒径。
