自组织多孔海绵状有机-无机杂化二氧化硅

Self-organized organic-inorganic hybrid silica sponge

经由溶胶-凝胶过程,利用硅试剂制备出新颖的多孔海绵状有机-无机杂化二氧化硅.使用冷场发射扫描电镜(FESEM),表征了多种反应条件下样品的形貌.这种杂化二氧化硅海绵体能快速吸收水和有机溶剂,每克能吸收12.2 mL溶剂.

A novel porous hybrid silica sponge constructed by structured-nanofiber bundles was prepared by sol-gel procedure. Field-emission scanning electron microscopy （FESEM） was utilized to characterize the shape of the products obtained at different reaction conditions. This sponge can absorb water and organic solvents （such as methanol, ethanol, acetone, eyelohexane, etc. ） in high speed. It absorbed 12.2 mL of solvents per gram.
