中文摘要: 本课题针对严重阻碍纳米金刚石应用的关键性问题,基于构性关联的分子设计,通过多步可控化学反应,合成出结构新颖的、以纳米金刚石为核、含三嗪环的第一至第五代树枝状高分子。该系列树枝状高分子能溶解于多种酸和有机溶剂,且随树枝状高分子结构的迭代构筑,纳米金刚石的分散性得到显著改善。在此基础上,考察了该系列树枝状高分子作为极压添加剂的摩擦学性能,并初步探讨了树枝状高分子结构与润滑性能之间的关系。

英文摘要: Aiming for a serious impediment to the application of nano-diamond, and based on the molecular structure associated design, novel first to fifth generation dendrimers, which contain triazine rings and core of nano-diamond, were synthesized through multi-step controllable chemical reaction in this subject. The series of dendrimers can be dissolved in a variety of acid and organic solvents, and with the iterative construction of the dendrimer structure, the dispersion of nano-diamond has been significantly improved. On this basis, we investigated the tribological properties of the series of dendrimers as extreme pressure additives, and discussed the relationship between dendrimer structure and lubricating properties.
