摘　　要：木材作为一类绿色可再生材料,广泛应用于室内装饰、户外木结构建筑等多个领域,由于长期光照致使木材结构老化、服务寿命降低,在木材表面构建紫外线屏蔽涂层十分重要。结合无机金属氧化物纳米粒子、层状金属氢氧化物纳米粒子、生物源类黑色素纳米粒子三类紫外线屏蔽纳米材料,针对纳米粒子在涂料中分散稳定性差、易团聚的问题,着重介绍利用核-壳包覆、主-客体组装等结构设计策略增强紫外线屏蔽纳米涂料性能的研究进展。并就紫外线屏蔽纳米涂料在木材耐光老化方面的研究与应用进行简要总结,为绿色、高效木质基材耐光老化涂料的研发提供思路。As a green renewable material,wood is widely applied in many fields such as indoor&outdoor decoration and structure construction.In order to solve the problem of aging and reducing service life caused by long-term exposure in light,the importance of constructing UV-resistant coatings on the surface of wood is elaborated.New requirements for high efficiency and high environmental tolerance are considered for the nano-UV-resistant coatings.In this review,we mainly introduced the research progress of nano metal oxides,layered double hydroxides and bio-derived melanin particles as the UV shielding agents.With respect to the poor dispersion stability and easy agglomeration of nanoparticles,the core-shell design,host-guest assembly and other structural design strategies were briefly introduced.The application of nano-UV-resistant coatings in wood anti-photodegradation were also summarized,which will promote the development progress in the research field of nano-UV-resistant coatings for green and efficient wood materials.
