荧光涂层的设计、制备与应用研究进展

荧光材料能够在紫外或可见光的作用下产生荧光,并已广泛应用于日常生活中.然而,由于荧光材料通常为小分子,在使用过程中存在易流失、效率低、功能单一等问题.针对这些问题,近年来研究人员将荧光物质与树脂等基质结合制备荧光涂层.综述了荧光涂层的设计、制备与应用的研究进展,重点介绍了荧光物质与涂层的结合方式以及基于不同种类荧光基团的荧光涂层设计与构建.结合方式分为物理掺杂和化学键合.荧光材料分为四大类,有荧光蛋白、有机荧光基团、稀土配合物和发光纳米粒子,不同的结合方式、不同种类的荧光材料各有优缺点,选择恰当的结合方式和荧光材料对发挥荧光材料的功能至关重要.荧光涂层在特定条件下可以发射出荧光,在外部刺激(如离子、作用力、pH变化等)作用下发射的荧光会产生变化,基于此可应用于如腐蚀预警、离子检测、防伪加密等.对荧光涂层在生物医药、金属防腐预警、防伪加密等方面的应用等进行了详细阐述,同时对荧光涂层未来发展做了展望.

Research Progress on Design, Preparation and Application of Fluorescent Coatings

Fluorescent materials can emit fluorescence under ultraviolet or visible light, which have been widely used in our daily life. However, fluorescent materials are usually small molecules, thus some problems such as easy loss, low efficiency and single function exist. In recent years, fluorescent substances have been combined with resins and other substrates to prepare fluorescent coatings to solve these problems. This article reviews the research progress of the design, preparation and application of fluorescent coatings, focusing on the combination of fluorescent substances and coatings, the design and construction of fluorescent coatings based on different types of fluorescent groups. The binding methods are divided into physical blending and chemical bonding and fluorescent materials can be divided into four categories, including fluorescent proteins, organic fluorescent groups, lanthanide complexes and luminescent nanoparticles. Different binding methods and different types of fluorescent materials have their own advantages and disadvantages, choosing the right combination and fluorescent material is very important for the function of fluorescent material. Fluorescent coatings can emit fluorescence under certain conditions, which can produce corresponding changes in the emitted fluorescence under external stimuli such as ions, force and pH changes. Due to the change of fluorescence under different conditions, it can be used for corrosion self-reporting, ion detection, anti-counterfeiting encryption, etc. Therefore, we describe carefully the application of fluorescent coating in biomedicine, metal anticorrosion warning, anti-counterfeiting encryption, and propose the future development of fluorescent coating.
