The article focuses on a research that explains the variation of friction in lubricated system by using graphene layers. It mentions that graphite is widely used in lubricated system as it has weak interlayer interaction strength that cause low friction. It reflects on the use of friction force microscopy (FFM) to study the nanostructure of graphene and mentions that graphene explains the phenomenon of wrinkle formation in lubricants and impact of layers or sheet size on friction.
