The present invention relates to a method for preparing composites of substrate-molecular sieve, in particular, to a method for preparing a composite of substrate-molecular sieve, which comprises applying a physical pressure to molecular sieve crystals against a substrate to form a chemical bond between the molecular sieve crystal and the substrate. The present invention requiring no solvents, reactors and other equipments enables molecular sieve crystals to be stably attached to the surface of substrates through various chemical bonds, particularly ionic present invention ensures the synthesis of substrate-molecular sieve composites with enhanced attachment rate, degree of lateral close packing (DCP) and attachment strength in more time-saving and energy-saving manners. The present method works well for molecular sieve crystals with lager sizes (e.g., more than 3 μm) with no generation of parasitic crystals. Furthermore, the present invention shows excellent applicability to large substrates, enabling the mass production of substrate-molecular sieve composites.
A method for preparing a composite of substrate-molecular sieve, which comprises applying a physical pressure to molecular sieve crystals against a substrate to form a chemical bond between the molecular sieve crystal and the substrate, and to align the molecular sieve crystals with a single orientation in a monolayer on the substrate, and the method further includes the substrate, the molecular sieve or the substrate and the molecular sieve linked to a linking compound.
