Abstract: The preparation of coating with good flexibility and high hardness had importantapplication value，however，it was difficult to balance the flexibility and hardness，which were contradictory properties. By combining the hard inorganic phase with the flexible organic phaseat the molecular level through organic-inorganic hybridization，the coating could obtain thepolymer-like flexibility and ceramic-like high hardness at the same time. Further endowing thecoating with functions such as transparency，hydrophobicity and oleophobicity，antifouling，and self-healing，could extend the applications of coating in flexible display devices and marineantifouling. This paper reviewed the research progress of functional flexible hard coating andsummarized the relationship between structure and property. Finally，the future of the field was expected. Realizing the multifunctional integration of coating and use in extreme environmentswould be an important research direction for functional flexible hard coating.

摘要： 制备兼具良好柔韧性与高硬度的涂层具有重要应用价值，然而大多数涂层很难在保持柔韧性的同时具备高硬度。通过有机 -无机杂化将高硬度的无机相与柔韧的有机相在分子水平上结合，使涂层同时具有类聚合物的柔韧性和类陶瓷的高硬度，且进一步赋予涂层功能，如透明、疏水疏油、防污、自修复等可拓展涂层在柔性显示设备和海洋防污等方面的应用。本文综述了功能性柔性硬质涂层的研究进展，并对其结构 -性能的关系进行了讨论。最后，展望了该领域的发展趋势。如何实现涂层多功能的集成和在极端环境下的使用将是功能性柔性硬质涂层的重要研究方向。
