金红石型纳米TiO_2紫外屏蔽性能的相关应用及改性研究

Application and surface modification of rutile nano titanium dioxide as UV-shielding agent

金红石型纳米TiO2对可见光的透射性强,具有极好的吸收、散射紫外线能力,可作为紫外屏蔽剂广泛应用于涂料、化妆品、纺织、木材加工等行业。但纳米TiO2同时也具有光催化性能,是有机基体发生光氧化的催化剂,且在有机基体中的分散性和稳定性不好,需经表面处理以解决这些问题。本文针对金红石型纳米TiO2防紫外性能的相关应用、存在的问题及改性研究进行了阐述。

Rutile nano titanium dioxide has strong capacities of transmission, light-scattering and optical absorption. It can be widely used in paints, cosmetics, textile,wood and other industries as UV-shielding agent. However, it also have the photocatalytic performance which causes polymer degradation, and it can not evenly distribute and stably exist in organic matrix. These problems need to be solved through the ways of surface modification. The related applications of rutile nano TiO2 UV-shielding performance, the problems and surface modification research were expound.
