摘要:
以聚丙烯纤维为增强相,与SiO2进行复合,经疏水改性与超临界CO2干燥制备超疏水聚丙烯纤维/SiO2气凝胶复合材料。采用N2吸附-脱附法、傅里叶变换红外光谱仪(FT-IR)、X线衍射仪(XRD)、扫描电子显微镜(SEM)、接触角测定仪对疏水性聚丙烯纤维/SiO2气凝胶复合材料的结构与性能进行表征。结果表明:所制得的样品比表面积为800 ~950 m2/g,平均孔径为8~13 nm,属于介孔材料。水接触角随改性剂浓度的增大而增大,且能达到超疏水水平。对各类油吸附倍率最高可达7.54倍,且具有一定的循环使用效率。
Abstract:
The superhydrophobic SiO2 aerogels composite was prepared by using polypropylene fiber as the reinforcing phase, compounding with SiO2 gel, and hydrophobically modifying and supercritical carbon dioxide drying. Characterization of the structure and properties of superhydrophobic polypropylene fiber/silica aerogel composites were carried out by N2 adsorption-desorption, Fourier transform infrared spectroscopy(FT-IR), X-ray diffractometry(XRD), scanning electron microscopy(SEM)and contact angle measuring instrument. Results showed that the prepared sample had specific surface areas of 800-950 m2/g and average pore size distributions between 8 nm and 13 nm, which was a mesoporous material. The water contact angle increased with increasing concentration of the modifier and could reach superhydrophobic levels. It had an adsorption efficiency of up to 7.54 for various types of oils and had a certain recycling efficiency.
