This contriburion is aimed at the preparation of new composite membranes with zeolite NaA layer on porous metal and metal-ceramic flexible supports, which have the advantages of higher conductivity, durability and lower price with respect to smooth alumina tubes. However surface roughness impedes continuous zeolite layer growth. Application of electric field assisted procedure in contrast with a standard hydrothermal synthesis allowed to obtain efficient NaA membranes on rough metal supports and significantly shortened their preparation time.
