Effects of Modified Graphene in Vegetable Oil on Friction and Wear Reduction

Abstract

A graphene allotrope is to be selected from 3 types of multilayer graphenes comprise of graphene nanoplatelets (GNP), nanostructured graphite (NSG) and multiwalled carbon nanotube (MWCNT). Each graphene allotrope was sonicated with high oleic POME into various graphene-oil nanofluids at same concentration. Modification of graphenes via sodium dodecyl sulphate (SDS) - oleic acid (OA) approach was conducted as well. The dispersion stability and friction performance of modified and non-modified graphenes in high oleic POME were studied
