This review report concerns the manufacturing of layered supportstructures for inorganic pervaporation and gas separation membranes by dip coating. The manufacturing of a ceramic layer on a porous support by dip coating is a processing step where the principles of colloidal processing are very important in order to achieve layers with few defects. In this review the mechanisms of layer formation on porous substrates using dip coating, colloidal filtration and film coating are explained. Practical aspects of the dip coating method are extensively dealt with. 87 refs.
