Polymer lubricants (PLs) are highly attractive lubricating materials for their excellent tribological properties. In this work, a novel ring-bridged polymer lubricant (PIBOA) was prepared from monomers of isobornyl acrylate (IBOA) and its tribological performance was evaluated, which indicates that the functional group of bridged cycloalkanes can control the coefficient of friction compared with the polymethyl methacrylate (PMMA) lacking the “hook” group. Moreover, the antiwear performance of PIBOA is similar to that of PMMA. The X-ray absorption near edge structure (XANES) analysis and rheological results reveal that the generation of a layer by layer sulfur-based tribofilm with different chemical compositions and the increase of shear viscosity result in excellent antiwear performance and the control of the coefficient of friction. The understanding of the tribology of bridged bicyclic polymers might shed light on the design and application of precision machinery.

桥联双环聚合物作为润滑剂的合成及其摩擦学行为

聚合物润滑剂（PLs）具有出色的摩擦学性能，是极具吸引力的润滑材料。本文从丙烯酸异冰片酯（IBOA）的单体制备了一种新型的环桥聚合物润滑剂（PIBOA），并对其摩擦学性能进行了评估，表明与聚甲基丙烯酸甲酯相比，桥联环烷烃的官能团可以控制摩擦系数。缺少“钩”基团的甲基丙烯酸酯（PMMA）。此外，PIBOA的抗磨性能与PMMA相似。X射线吸收近缘结构（XANES）分析和流变结果表明，具有不同化学组成的逐层硫基摩擦膜的产生以及剪切粘度的增加，导致优异的抗磨性能和对碳纤维系数的控制。摩擦。
