通过生物润滑剂和复杂的纳米结构表面共同作用,在滑膜关节中实现了极其有效的润滑系统。分子瓶刷结构对这种上级摩擦系统起着至关重要的作用。例如,润滑素是重要的生物润滑剂,并且与透明质酸相关的聚集蛋白聚糖对于软骨的机械响应是重要的。受大自然的启发,合成瓶刷聚合物已被开发出来,并实现了出色的水边界润滑。在这篇综述中,我们总结了最近的实验研究的表面涂有瓶刷生物润滑剂和bioinspired瓶刷聚合物的界面润滑性能。我们还讨论了最近的进展,了解分子间协同作用的水性润滑,包括天然和合成聚合物。最后,发展高效的水边界润滑系统的机遇和挑战。
An extremely efficient lubrication system is achieved in synovial joints by means of bio-lubricants and sophisticated nanostructured surfaces that work together. Molecular bottlebrush structures play crucial roles for this superior tribosystem. For example, lubricin is an important bio-lubricant, and aggrecan associated with hyaluronan is important for the mechanical response of cartilage. Inspired by nature, synthetic bottlebrush polymers have been developed and excellent aqueous boundary lubrication has been achieved. In this review, we summarize recent experimental investigations of the interfacial lubrication properties of surfaces coated with bottlebrush bio-lubricants and bioinspired bottlebrush polymers. We also discuss recent advances in understanding intermolecular synergy in aqueous lubrication including natural and synthetic polymers. Finally, opportunities and challenges in developing efficient aqueous boundary lubrication systems are outlined.
