摘要/Abstract

摘要：

通过乳液法成功制备了具有开放孔隙结构的介孔氧化硅（OSMS）。通过扫描电子显微镜（SEM）、透射电子显微镜（TEM）和氮气吸附-脱附测试（BET）对其微观结构进行系统分析，证实OSMS具有单分散颗粒（粒径0.40 μm）、开放的孔道结构、均一介孔分布（孔径24.4 nm）、高比表面积（162 m²/g）和大孔容（1.12 cm³/g）等特性。性能研究结果显示，在对10种不同油脂的吸油值测试中，OSMS表现出较好的吸附性能优势，其吸油值分别是多孔硅150H的1.3~1.9倍、有机硅弹体KSP-100的3.3~6.3倍，以及淀粉类TAPIOCA的6.0~7.5倍。人体皮肤控油实验表明，OSMS具有快速吸附和长效维持特性，且控油效果与用量呈线性正相关（R²>0.95）。体外SPF值测试显示，OSMS具有防晒增效作用，0.3% （w/%） OSMS就可以提高防晒霜的SPF值。

Abstract:

An open-pored mesoporous silica （OSMS） was successfully prepared by emulsion method. Its microstructure was analyzed using scanning electron microscopy （SEM）, transmission electron microscopy （TEM）, and nitrogen adsorption-desorption tests （BET）. The results showed that, the OSMS particles were monodisperse, and the particle size was 0.40 μm; the product had open channel structure and uniform mesopore size distribution （pore diameter of 24.4 nm）; OSMS had high specific surface area （162 m²/g） and large pore volume （1.12 cm³/g）. The results of performance study indicated that, in the oil absorption value test for 10 different oils and fats, OSMS demonstrated superior adsorption performance. Its oil absorption values were 1.3-1.9 times that of porous silica 150H, 3.3-6.3 times that of silicone elastomer KSP-100, and 6.0-7.5 times that of the starch-based TAPIOCA, respectively. Human skin oil-control experiments indicated that OSMS had the features of rapid and long-lasting adsorption, and the oil-control effect was linearly and positively correlated with the dosage （R²>0.95）. In vitro SPF value tests showed that OSMS had sun-screening synergistic effect, and just 0.3% （w/%） OSMS could increase the SPF value of a sunscreen. This work might provide experimental support for the application of OSMS as an oil-control raw material and a sun-screening synergist in cosmetics.

Key words: emulsion method, open pore structure, mesoporous silica, adsorption performance, synergistic sun-protection effect
