Abstract
The application of polymer nanocomposites (PNCs) in lubricant industry has attracted considerable interest due to their much enhanced properties compared to neat polymers. In this study, magnetite (Fe3O4) nanoparticles (NPs) were synthesized. Then PNCs were prepared by reinforcing these NPs in the homopolymer of dodecyl acrylate in different percentages. The characterization of the prepared NPs and PNCs was done by different analytical techniques. Thermal stability is determined through thermogravimetric analysis (TGA). Performance evaluation of the PNCs as viscosity index improver, pour point depressant and antiwear additive was carried out by blending them with a mineral base stock at different percentage ratios. Standard ASTM methods are followed to carry out the evaluations. It is found that with increasing the percentage of nanocomposites in the base stock, the overall performance of the furnished lubricant is enhanced.

This shifting of carbonyl stretching frequency may be due to some association of nanomagnetite and poly dodecyl acrylate
The lubricant blended with 5% Fe3O4 nanocomposite (F-3) additive showed highest increment (42.7%) in viscosity index compared to pure base oil
Summary
The application of polymer nanocomposites (PNCs) in lubricant industry has attracted considerable interest due to their much enhanced properties compared to neat polymers. Nanoparticles were incorporated into lubricating oils to improve their tribological properties. Cai-Xiang et al.[18] reported the anti-wear and friction reducing properties of C eO2 and TiO2 nanoparticles in lubricating oil.
