Abstract
The invention is comprised of a procedure for applying molecular sieve films to the surface of different substrates. This procedure is characterized in that microcrystals of the molecular sieves in question bind to the substrate surface in a first step as a monolayer, and are then, in a second step, allowed to grow into a thin, continuous and dense film. Molecular sieve films are of interest in application areas such as preparing membranes, catalysts, sensor devices and polymer reinforcing fillers.
