中文摘要：

有机高分子材料是一类重要的文物保护材料,但由于自身稳定性的限制,在紫外线照射下常发生光老化现象。因此,利用光稳定剂对其进行改性,对高性能文物保护材料的研制具有重要意义。综述了有机高分子文物保护材料的光老化机理和紫外线吸收剂、受阻胺、纳米光屏蔽剂3类常用稳定剂的稳定机理,并阐述了其在文物保护材料改性中的应用。

英文摘要：

Organic polymers are vital conservation materials used in cultural heritage.However,due to their own limitation on stability,photo-degradation often occurs under the radiation of UV rays.Thus,it is very necessary to modify organic polymers using light stabilizers.The photo-degradation mechanism of the polymers and the stabilization mechanisms of three kinds of common polymeric stabilizers,namely ultraviolet absorbents,hindered amine light stabilizers and nano light screening agents,are reviewed.And their application in modifying materials used in the field of historic relics conservation are further described.
