【摘要】 丁二酰亚胺类分散剂是一种典型的用于各种润滑油中的无灰分散剂。由于烟炱颗粒结构的复杂性,从实验研究的角度对分散剂的作用机理尚未给出满意的解释。本文应用分子动力学模拟方法,研究了丁二酰亚胺类分散剂模型分子在伪烟炱表面的吸附行为。模拟结果可以为分散剂的分子设计提供参考。更多还原

【Abstract】 Succinimide dispersants are typical ashless dispersants in various lubricants. Due to the complex structure of soot particles, there were no satisfying explanations for dispersants’ dispersancy from the experiment study. Molecular Dynamics simulation was used in this paper to study the adsorption behaviors of various succinimide dispersants on pseudo-soot surface. Simulation results can give reference to the molecular design of dispersants.更多还原
