Nanomaterials Derived from a Copper Cinnamate Complex with 4′-Phenyl-2,2′:6′,2″-terpyridine as Antifriction and Anti-Wear Additives for Oil Lubricants

In the present study, a facile and easily accessible method for obtaining copper-containing nanomaterials by thermolysis of copper cinnamate complex with 4′-phenyl-2,2′:6′,2″-terpyridine at 300 °C was developed. The obtained nanomaterials were studied using X-ray diffraction, atomic force microscopy, scanning electron microscopy and energy dispersive analysis. Analysis of copper-containing nanomaterials as additives to lubricant (liquid paraffin) was carried out from the point of view of their tribological behavior using pin-on-disc and four ball friction machines. At optimum concentration of nanomaterials, the friction coefficient is the lowest. The mechanism of friction in the presence of the studied lubricant compositions is discussed. Graphic Abstract
