Preparation of Copper‐containing Nanocomposites by Thermolysis of Copper (II) Complex and Their Use as Anti‐friction and Anti‐wear Additives to Lubricant Oils

Abstract

AbstractA simple and accessible method has been developed for the preparation of copper‐containing nanocomposites by thermolysis of a copper(II) complex with a Schiff base based on 3‐formyl‐4‐hydroxycoumarin and octadecylamine at 500 °C. The resulting nanoparticles with a particle size of up to 85 nm were used as additives to lubricants. It has been established that copper oxide nanoparticles with a concentration of 0.5 % and 1 % increase the anti‐wear and anti‐friction properties of the lubricant.
