A graphene platelet comes in between two steel contact during sliding under loads of 200N and 210N . The Coefficient of friction measured with 210N is less than 200N.
I had a mineral oil of 460cSt (containing sulphur and phosphorus), after addition of nanparticles (carbon nano tubes and graphene) the viscosity decreased significantly. literatures says that the...
