[ABSTRACT ]

Due to the strong Van der Waals force, agglomeration will occur to nanoparticles, which added into bio lubricant. Although some studies show that homogeneity in the mixture does not have a significant effect on lubricant behavior in friction reduction, but a more stable mixture is more expected. In experiments, the agglomeration that occurs is observed visually. The disadvantage is that this method is considered inefficient because of time-consuming. This study is aimed to assess this agglomeration phenomenon using molecular dynamics simulation methods. The simulation results show that mixtures of TMPTO with less than 0.4wt% hBN additions have a good dispersibility.
