Silsesquioxane aerogels are well-known porous materials for their low density, large porosity and high specific surface area. Silica aerogels functionalized with organosilane molecules having amino groups has been widely studied. However, the number of amino groups in organosilane molecules is limited. To further improve the sorbent performance and explore new sorbents, the incorporation of polymers into silica aerogels is a promising approach due to the improvement of reactive sites. In recent years, aerogels materials impregnated with branched polyethyleneimine (PEI) has been studied. However, adsorbents prepared by wet impregnation are difficult to apply in liquid systems. In this work, we describe a system where amine functionality is introduced into silsesquioxane aerogels by cross-linking reaction. The pollutant removal performance of these newly designed silsesquioxane aerogels was studied. |
