Presented at: International Symposium on Inorganic Interfacial Engineering, Stockholm, Sweden, 20-21 juni 2006.

The key factor in obtaining defect free macroporous membrane supports is found in the application of multiple inorganic suspension coatings rather than the use of a single somewhat thicker macroporous layer. Colloidal processing plays an important role in achieving such a multiple layer system. Finding the optimal coating conditions is, however, not a trivial task. In this presentation we discuss possible processing routes to obtain virtually defect free multiple layer systems through the use of design of experiments (DoE) in finding suitable coating conditions.
