纳米TiO2在聚合物抗紫外光老化中的研究进展

摘要

纳米TiO2作为一种新型的无机纳米材料,具有无毒、无味、耐水、稳定性好等特点,同时也可作为紫外线屏蔽剂应用于涂料、塑料、橡胶等方面.简要论述了纳米TiO2的紫外光吸收性能,并着重介绍了纳米TiO2在聚合物抗紫外光老化方面的应用,最后就目前纳米TiO2应用过程中存在的问题进行了阐述.%As a new type of inorganic nanomaterials,nano-TiO2 is non-toxic,odorless,and water resistant,etc.Meanwhile,it also can be used as ultraviolet screening agent,which can be applied in coatings,plastic,rubber,etc.The ultraviolet absorption properties of nano-TiO2 was briefly discussed,and the application of nano-TiO2 used in the UV aging resistance of polymer was emphatically introduced.Finally,the problems existing in the process of application was also stated.
