Abstract

This PhD thesis describes the development and separation properties of the composite membrane system -alumina(macroporous)/¿-alumina(mesoporous)/hybrid silica (microporous). The influence of chemical modification of the surface and pores of the mesoporous and microporous layers of the membrane by covalently bonded organic groups was studied. Two synthesis strategies to make more hydrophobic layers have been followed in this regard. The first is grafting of the surface of the intermediate mesoporous layer with organochlorosilanes, the second one is the in situ hydrolysis and condensation of organosilane precursors to prepare microporous top layers.
