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
