摘要:

首先制备了一种亚微米花状二氧化钛,依次对其进行无机和有机表面处理后制得TiO2/Al(OH) 3/SS复合材料(TAS),最后在TAS表面包覆一种天然防晒剂姜黄素(Cur),得到最终产物TASC复合材料。通过XRD、UV-Vis、TEM、FT-IR、水接触角等技术手段对所得样品进行表征,结果表明:Al(OH) 3、SS、Cur均以非晶态和物理吸附的形式包覆于TiO2表面,三者的适宜包覆量分别为8%,8%和6%;防晒指数分析表明:TASC的紫外屏蔽能力远强于市售亚微米TiO2(CR-50),接近市售纳米TiO2 (626B)。此外,与TAS相比,TASC复合材料还具有较强的抗氧化性。

Abstract:

In this study, a sub-micron flower-like titanium dioxide was first prepared, followed by inorganic and organic surface treatment to prepare TiO2 /Al(OH) 3 /SS composite (TAS). Finally, the surface of TAS was coated with curcumin (Cur), a natural sunscreen, to obtain the final product-TASC composite. The samples were characterized by XRD, UV-Vis, TEM, FT-IR and water contact angle. The results show that Al(OH) 3, SS and Cur are all coated on the TiO2 surface in the form of amorphous state and physical adsorption, and the suitable coating amounts of the three are 8%, 8% and 6%, respectively. The UV shielding ability of TASC is much stronger than that of the commercial submicron TiO2 (CR-50) and close to the level of the commercial nano TiO2 (626B). In addition, compared with TAS, TASC composite also has strong oxidation resistance.

Key words: submicron TiO2, curcumin, ultraviolet shielding, efficacy
