Sol-gel strategies for the preparation of inorganic membranes involve the deposition of an inorganic sol on a mesoprous support by a process combining the features of slip-casting and dip-coating. In order to be practical the deposited membrane must exhibit both high flux and high selectivity. For porous membranes these requirements are met by extremely thin, porous films exhibiting a narrow size distribution of very small pores. This paper considers the use of polymeric silica and hybrid-organosilyl precursor sols in the context of the underlying physics and chemistry of the membrane deposition process.
