Description
Summary:Stability of nanolubricants is a basic requirement for heat transfer application since it is directly related to the properties of nanolubricants. However, the particle suspension is the major issue of creating a new nanolubricant. The objective of the present study is to compare the effect of different dispersion methods on the stability of graphene in polyester oil-based lubricant. Nanolubricant are prepared by different two-step method, including magnetic stirrer, overhead stirrer, and sonication. The stability of nanolubricant was measured by sedimentation observation, metallographic microscopy, and zeta potential. The results show that the overhead stirrer method was the most effective at providing a more stable suspension.
