动物关节的超低摩擦系数和长耐磨寿命主要归功于关节软骨表层以及关节滑液中呈“刷”型结构的生物大分子.人工仿制的表面接枝聚合物刷可以对关节润滑进行功能模拟,本文简要综述了近年来表面接枝聚合物刷的水润滑研究进展.重点讨论了不同类型聚合物刷(天然生物大分子、聚电解质刷、两性离子聚合物刷和中性聚合物刷等)的水润滑机理,最后讨论了目前仿生水润滑研究存在的问题以及未来的发展趋势及应用前景.
The ultra-low coefficient of friction and long wear life of animal joints are attributed to the “brush” -like biological macromolecules in the surface of articular cartilage and synovial fluid. Artificial surface-grafted polymer brush can be used for joint lubrication In this paper, the recent progress in the water lubrication of surface-grafted polymer brushes is reviewed in this paper.Focusing on different types of polymer brushes (natural biomacromolecules, polyelectrolyte brushes, zwitterionic polymer brushes and neutral polymer brushes Etc.). Finally, the problems existing in the study of bionic water lubrication and the future development trends and application prospects are discussed.
