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.
