Abstract

In this thesis, the synthesis of inorganic - polymeric hybrid membranes by sequential grafting is discussed, for application in gas separation. At high pressures and temperatures, organic (olymer) membranes may suffer from swelling and plasticization. Generally, this causes a reduced molecular selectivity of organic membranes. Confining the organic in a thermo-mechanically stable porous material may aid moderating plasticization and swelling. Here, it is investigated if sequential chemical grafting of precursors in the pores of a meso-porous ceramic support will allow such confinement.
