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.

[ What is claimed is:] [1.] A method of preparing a monolayer structure comprising molecular sieve microcrystals which method comprises;a) preparing a dispersion comprising discrete microcrystals of molecular sieve which have a surface charge,b) selecting or preparing a substrate with a surface charge which is opposite to that of the discrete microcrystals in the dispersion,c) contacting the substrate with the dispersion comprising discrete microcrystals of molecular sieve such that discrete microcrystals of molecular sieve are attracted to and adhere to the substrate as a monolayer.
