The dispersion of nanomaterials in lubricating oil plays an important role in the lubrication and wear-resistance properties. In this work. supramolecular layered double hydroxides (LDHs) were prepared and added to lubricating oil with different dispersants. The content of key elements in the samples was measured by an oil element analyzer. https://www.ensemblecarpediem.com/product-category/cupcake-and-cake-boxes/
