摘　　要：液晶聚合物(LCP)的分子基元按液晶顺序排列,因此液晶聚合物(LCP)具有光学、电学以及力学性质的各向异性。引入响应性化学基团后,LCP涂层具有刺激响应性,能够对光、热和电场等刺激做出响应。LCP涂层能够在外界刺激下智能调控其表面形貌,调节表面的摩擦和润滑性质,并影响细胞的生长和分化行为。本文回顾了液晶聚合物涂层的最新进展,重点介绍了其在调控表面摩擦和润滑性质以及在生物医用方面的应用。同时,展望了液晶聚合物涂层在未来发展中的应用前景,并指出了需要解决的科学问题。Liquid crystal polymer(LCP)has anisotropy in optical,electrical and mechanical properties because its molecular units are arranged in a liquid crystal order.After the introduction of responsive chemical groups,LCP coatings have stimulus responsiveness and can respond to stimuli such as light,heat and electric fields.The LCP coating can intelligently regulate its surface topography under external stimulation,adjust the friction and lubrication properties of the surface,and affect the growth and differentiation behavior of cells.This article reviews the latest advances in scientific research on liquid crystal polymer coatings,focusing on their applications in regulating surface friction and lubrication properties and in biomedical applications.At the same time,the article looks forward to the application prospects of liquid crystal polymer coatings in future development and points out the scientific issues that need to be solved.
