新型紫外线吸收剂研究进展

Research Progress in New Ultraviolet Absorbers

随着臭氧层的不断被破坏,使得人类暴露于更高水平的紫外线辐射中。紫外线吸收剂能吸收特定波长的紫外线,可应用于多个领域防护紫外线的破坏。为解决紫外线吸收剂难溶于水、与其他高分子材料相容性差、反应活性差等问题,研究人员对紫外线吸收剂做了很多改进和修饰,本文概述了近五年来新型三嗪类、苯并三唑类、二苯甲酮类紫外线吸收剂的新结构和应用。

As the ozone layer continues to be destroyed,it exposes humans to higher levels of UV radiation.UV absorbers can absorb specific wavelengths of ultraviolet radiation and can be used in a variety of fields to prevent the damage caused by ultraviolet light.In order to solve the problems of UV absorbers being difficult to dissolve in water,poor compatibility with other polymer materials,easily absorbed by skin,and poor reaction activity,researchers have made a lot of improvements and modifications to UV absorbers,and this paper summarizes the syntheses and applications of new UV absorbers in the last five years.
