摘要:

通过超声水解法制备了SiO2包覆的SiO2/TiO2纳米材料,研究了不同热处理温度对SiO2/TiO2纳米材料性能的影响,测试发现SiO2/TiO2纳米材料结构未发生变化,均为金红石型TiO2,SiO2包覆后通过物理包覆作用与TiO2发生了结合。微观测试发现SiO2/TiO2材料均为球形颗粒,直径为1.5~2 μm,随着热处理温度的增加,尺寸轻微增大。亲水亲油测试表明SiO2/TiO2纳米材料具有较强的亲油性。其对亚甲基蓝的褪色率低于纯TiO2,随着热处理温度的增加,褪色率先降低后升高,550 ℃处理的SiO2/TiO2纳米材料对亚甲基蓝的褪色率最低为18.7%。将SiO2/TiO2纳米材料自制成防晒乳液,其对于紫外光屏蔽效果优于纯TiO2,热处理温度为550 ℃时,复合材料的透射率最低,对紫外光的屏蔽效果最佳。综合来看,SiO2包覆后的SiO2/TiO2复合材料在防晒化妆品的应用中具有较高的潜力。

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.
