Abstract:

SiO2-coated SiO2/TiO2 nanomaterials were prepared by ultrasonic hydrolysis. The effects of different heat treatment temperatures on the properties of SiO2/TiO2 nanomaterials were studied. It was found that the structure of SiO2/TiO2 nanomaterials did not change, and they were all rutile-type TiO2. SiO2 was combined with TiO2 by bonding after SiO2 coating. The results of microscopic test showed that the SiO2/TiO2 materials were spherical particles with diameter of 1.5-2 μm, and the size was slightly increased with the increase of heat treatment temperature. Hydrophilic and lipophilic tests showed that the SiO2/TiO2 nanomaterials had strong lipophilicity. The fading rate of methylene blue by SiO2/TiO2 nanomaterials was lower than that of pure TiO2. With the increase of heat treatment temperature, the fading rate first decreased and then increased. The fading rate of methylene blue by SiO2/TiO2 nanomaterials treated at 550 ℃ was the lowest (18.7%). The SiO2/TiO2 nanomaterials were introduced into sunscreen lotions, indicative of better UV shielding effect than pure TiO2. When the heat treatment temperature was 550 ℃, the transmittance of the composite material was the lowest and the UV shielding effect was the best. Overall, the SiO2/TiO2 composites coated with SiO2 had high potential of application in sunscreen cosmetics.
