The characterization analysis of multi walled carbon nanotubes coated with carboxylic group compounds to improve its dispersion properties in mineral base engine oils

Abstract

This paper describes the impact of adding lubricant additives on the viscoelastic and thermo-physical properties of engine oils. From the literature survey it was deduced that there was a need to fully understand how nano-tubes based lube oil solutions will behave mechanically and thermally and one needs devoted work for better and detailed experimentation. New additives are under development to improve wear and tear properties of engine components, fuel efficiency and to reduce carbon emissions from cars and commercial vehicles by reducing friction. To prolong the lifetime and maintain the efficiency of exhaust car emission reduction devices, the modern engine oils must contain low sulphated ash, phosphorus and sulfur. It is quite obvious from the detailed research papers analysis that the researchers are still pretty far from achieving full potential these nanotubes have. The environment is taking toll because of the use of harmful lubricants and the issue needs to be addressed through proper studies. The compatibility of nano particles with lubricants synergistic effect with many forms of lubricant oils needed to be further investigated. The structural characteristics needed to be explored and understood in more details with firmly evidence with the help of modern analytic methods, such as Scanning Electron Microscopy and Field Emission Scanning Electron Microscopy.
